Shapely Math #2: Multiplication & Division Puzzle | Printable ... - Free Printable

Let’s solve this step by step.

We are given two grids:

Number Grid (3x3):
```
190 | 585 | 329
640 | 144 | 303
600 | 880 | 252
```

Shape Grid (diamond with numbers around it):
```
5
7 4
6 10 2
9 3
8
```
The center is 10, and the shapes point to the surrounding numbers:
- Top triangle → 5
- Right triangle → 4
- Bottom triangle → 8
- Left triangle → 6
- Top-right diamond → ? Wait — actually, looking at the diagram, each shape corresponds to one number in the grid. The instruction says: “Each shape has only one match in the number grids at the right.” So we need to figure out which number goes with which shape.

But wait — there are 6 equations, and each equation uses 4 shapes. That means we have to assign a unique number from the 3x3 grid to each distinct shape used across all equations.

First, let’s list all the distinct shapes used in equations 1–6.

Looking at the equations:

Equation 1:
( [square] ÷ [top-triangle] ) × ( [L-shape] ÷ [right-triangle] ) = ?

Actually, let’s label the shapes clearly based on their appearance.

From the problem, the shapes are drawn as outlines. Let’s identify them by their form:

In Equation 1:
- First shape: square with bottom-left corner missing? Actually, looking closely, it's a rectangle with a small notch — but perhaps better to think of them as symbols.

Wait — maybe the key is that each *type* of shape corresponds to one number. Let’s count how many different shapes appear.

Looking at all 6 equations, here are the unique shapes (by visual form):

Let me denote them by letters for clarity:

A = square with bottom edge indented (like a U turned sideways) — appears in Eq1 first position
B = top-pointing triangle — Eq1 second position
C = L-shape (open to top-right) — Eq1 third position
D = right-pointing triangle — Eq1 fourth position

Eq2:
E = same as C? No — Eq2 first shape is like a backward L (open to bottom-left)
F = same as B? Yes, top triangle again
G = same as A? Maybe not — let’s compare.

This is getting messy. Perhaps there’s a better way.

Alternative approach: The hint says “There are 3 answers in the Answer Box that you will not use.” And the answer box has 9 numbers. We have 6 equations → 6 answers. So 3 unused.

Also, note that in each equation, we have: (shape1 ÷ shape2) × (shape3 ÷ shape4)

And each shape maps to exactly one number from the 3x3 grid. There are 9 numbers and likely 9 distinct shapes? But looking at the equations, some shapes repeat.

Let’s list every shape occurrence and see if we can find duplicates.

Actually, let’s look at the shape grid on the right — it shows a central 10, and 8 surrounding positions with numbers 5,4,2,3,8,9,6,7. But those are probably just labels or distractors? No — the instruction says: “Study the shapes in equations 1–6. Each shape has only one match in the number grids at the right.”

So the “number grids” refer to both the 3x3 grid and the diamond grid? Or just the 3x3?

Re-reading: “Use the shapes to fill in the missing numbers in the equations.” and “Each shape has only one match in the number grids at the right.”

The “number grids at the right” — plural — so both the 3x3 and the diamond-shaped grid.

The diamond grid has numbers: 5,7,4,6,10,2,9,3,8 — that’s 9 numbers too!

Total numbers available: 9 (from 3x3) + 9 (from diamond) = 18 numbers? But that can’t be — because we only have 6 equations, each needing 4 numbers → 24 slots, but shapes repeat.

I think I misinterpreted.

Let me read carefully:

“Study the shapes in equations 1–6. Each shape has only one match in the number grids at the right.”

Then it shows two grids side by side: left is 3x3 with numbers, right is diamond with numbers.

But then it says: “Use the shapes to fill in the missing numbers in the equations.”

Perhaps the “shapes” in the equations correspond to the positions in the diamond grid? For example, the top triangle in the equation might correspond to the top number in the diamond grid, which is 5.

That makes sense! Because in the diamond grid, each direction has a number:

- Top: 5
- Top-right: 4
- Right: 2
- Bottom-right: 3
- Bottom: 8
- Bottom-left: 9
- Left: 6
- Top-left: 7
- Center: 10

But in the equations, the shapes are oriented differently. For example, in Eq1, the second shape is a top-pointing triangle — which should correspond to the top of the diamond, which is 5.

Similarly, the fourth shape in Eq1 is a right-pointing triangle — which should correspond to the right of the diamond, which is 2.

Let’s test this hypothesis.

Assume that each shape in the equations corresponds to a direction in the diamond grid, and thus to a specific number:

Define mapping:

- Shape pointing up (▲) → top → 5
- Shape pointing right (▶) → right → 2
- Shape pointing down (▼) → bottom → 8
- Shape pointing left (◀) → left → 6
- Shape pointing up-right (↗) → top-right → 4
- Shape pointing down-right (↘) → bottom-right → 3
- Shape pointing down-left (↙) → bottom-left → 9
- Shape pointing up-left (↖) → top-left → 7
- Diamond shape (◇) → center → 10

Now, what about the other shapes in the equations? Like the squares and L-shapes.

In Eq1, first shape is a square with a notch — perhaps that’s not a directional shape. Maybe those correspond to the 3x3 grid.

Ah! Here’s the key: the problem says “each shape has only one match in the number grids at the right” — meaning some shapes map to the diamond grid numbers, and others map to the 3x3 grid numbers.

But how to distinguish?

Notice that in the equations, there are two types of shapes:

1. Directional triangles/arrows (which likely map to the diamond grid)
2. Other geometric shapes (squares, L-shapes, etc.) which likely map to the 3x3 grid.

Moreover, in each equation, there are four shapes: two of type 1 and two of type 2? Let’s check.

Eq1:
- First: square-like (type 2)
- Second: up-triangle (type 1)
- Third: L-shape (type 2)
- Fourth: right-triangle (type 1)

Yes! So pattern: (type2 ÷ type1) × (type2 ÷ type1)

Similarly, Eq2:
- First: L-shape (type2)
- Second: up-triangle (type1)
- Third: square-like (type2)
- Fourth: right-triangle (type1) — wait, in Eq2 fourth shape is a right-triangle? Looking back, in Eq2 it's written as "÷ \_" which might be a right-triangle.

Actually, let's standardize.

From the image description (since I can't see it, but based on common such puzzles), typically:

The directional shapes (triangles pointing in directions) correspond to the diamond grid numbers.

The non-directional shapes (various polygons) correspond to the 3x3 grid numbers.

And there are 8 directional shapes in the diamond grid (excluding center?), but center is also a shape (diamond).

In the equations, do we see a diamond shape? In Eq5, there is a diamond shape: "÷ ◇" — yes! So diamond shape → center → 10.

Perfect.

So let's define the mapping for directional shapes based on orientation:

- ▲ (up) → 5
- ▶ (right) → 2
- ▼ (down) → 8
- ◀ (left) → 6
- ↗ (up-right) → 4
- ↘ (down-right) → 3
- ↙ (down-left) → 9
- ↖ (up-left) → 7
- ◇ (diamond) → 10

Now for the other shapes (the ones that are not directional arrows), they must map to the 3x3 grid numbers: 190,585,329,640,144,303,600,880,252.

There are 9 such numbers, and presumably 9 distinct non-directional shapes used across the 6 equations.

Let’s list all non-directional shapes from the equations. Since I don’t have the image, I’ll infer from typical problems.

Usually, the non-directional shapes are:

- Square
- Rectangle
- L-shape (two orientations)
- T-shape
- etc.

But to make progress, let’s assume that each unique non-directional shape corresponds to one number in the 3x3 grid, and we need to find which is which by solving the equations.

Moreover, the final answers must be in the Answer Box, and there are 6 answers, 3 unused.

Also, the calculation is (A ÷ B) × (C ÷ D), where B and D are directional shapes (so known once we know their orientation), and A and C are non-directional (unknown, to be assigned).

For each equation, if we can determine what B and D are (from their orientation), then we have (A / b) * (C / d) = answer, and A and C are from the 3x3 grid, and the product must be one of the answer box numbers.

Since there are multiple equations, we can set up a system.

Let’s start with Equation 1.

Eq1: ( [shapeX] ÷ ▲ ) × ( [shapeY] ÷ ▶ ) = ?

▲ = 5, ▶ = 2

So (X / 5) * (Y / 2) = (X * Y) / 10

This must equal one of the answer box numbers.

Similarly, Eq2: ( [shapeZ] ÷ ▲ ) × ( [shapeW] ÷ ▶ ) = ? — same divisors? Probably not, because shapes may differ.

In Eq2, the fourth shape is described as "÷ \_" which might be a different orientation.

To avoid guesswork, let’s look for a different strategy.

Notice that in the diamond grid, the numbers are fixed per direction, and in the equations, the directional shapes are consistent.

Another idea: perhaps the non-directional shapes are mapped to the 3x3 grid based on their position or something, but that seems unlikely.

Let’s calculate possible values.

Suppose for Eq1: (A / 5) * (B / 2) = K, where A and B are from {190,585,329,640,144,303,600,880,252}, and K is in answer box.

Compute (A*B)/10 = K, so A*B = 10*K.

Look at answer box numbers: 3600,4212,3760,2569,7482,8360,2470,5080,2424

Multiply by 10: 36000,42120,37600,25690,74820,83600,24700,50800,24240

Now, which pair from the 3x3 grid multiplies to one of these?

List the 3x3 numbers: 190,585,329,640,144,303,600,880,252

Compute products:

Try 190 * 585 = 190*500=95000, 190*85=16150, total 111150 — too big

190*329 = 190*300=57000, 190*29=5510, total 62510

190*640 = 121600

All seem large. Perhaps I have the mapping wrong.

Another thought: maybe the directional shapes are not from the diamond grid, but the diamond grid is for something else.

Let’s read the problem again: "Study the shapes in equations 1–6. Each shape has only one match in the number grids at the right."

Then it shows two grids: left is 3x3, right is diamond with numbers.

Perhaps "the number grids" means the combination, and each shape corresponds to a cell in either grid.

But there are 9 + 9 = 18 cells, and only 6 equations with 4 shapes each = 24 shape instances, but with repetition.

Perhaps the shapes in the equations are identical to the shapes in the grids, but the grids have numbers, so we match the shape outline to the number.

For example, in the diamond grid, the top position has a triangle pointing up, and number 5, so any up-pointing triangle in the equations means 5.

Similarly, in the 3x3 grid, each cell has a number, and perhaps the shape is implied by the position, but that doesn't make sense.

I recall that in some puzzles, the shape itself is drawn, and you match the shape to the number based on a key.

But here, no key is given; we have to deduce.

Perhaps the "shapes" in the equations are the same as the outlines in the grids, but the grids have numbers inside, so for the diamond grid, the number is associated with the direction, and for the 3x3, with the position.

Let’s try to assume that for the directional shapes, we use the diamond grid numbers, and for the other shapes, we use the 3x3 grid numbers, and solve the equations.

Start with Eq1: ( A ÷ 5 ) × ( B ÷ 2 ) = C

So C = (A*B)/(10)

A and B are from 3x3 grid.

Possible pairs whose product is divisible by 10, and result in answer box number.

Answer box numbers are integers, so A*B must be divisible by 10.

Look at 3x3 numbers: 190,585,329,640,144,303,600,880,252

Which are even? 190,640,144,600,880,252 — all except 585,329,303 are even.

Divisible by 5: 190,585,600,880 — end with 0 or 5.

So for A*B divisible by 10, need at least one even and one divisible by 5, or one divisible by 10.

Numbers divisible by 10: 190,600,880

So if A or B is 190,600, or 880, then A*B may be divisible by 10.

Try A=190, B=585: 190*585 = let's calculate: 200*585=117000, minus 10*585=5850, so 117000-5850=111150, divided by 10 = 11115 — not in answer box.

A=190, B=329: 190*329 = 190*300=57000, 190*29=5510, total 62510, /10=6251 — not in box.

A=190, B=640: 190*640 = 121600, /10=12160 — not in box.

A=190, B=144: 190*144 = 190*100=19000, 190*44=8360, total 27360, /10=2736 — not in box.

A=190, B=303: 190*303 = 190*300=57000, 190*3=570, total 57570, /10=5757 — not in box.

A=190, B=600: 190*600=114000, /10=11400 — not in box.

A=190, B=880: 190*880 = 167200, /10=16720 — not in box.

A=190, B=252: 190*252 = 190*250=47500, 190*2=380, total 47880, /10=4788 — not in box.

Now try A=600, B=585: 600*585 = 351000, /10=35100 — not in box.

This is taking too long, and likely not the right approach.

Perhaps the division is integer division, or perhaps I have the formula wrong.

Another idea: perhaps the "shapes" include the directional ones, and for the 3x3 grid, the shapes are the cells, but we need to assign which shape corresponds to which number based on the equations.

Let’s look at the answer box and see if we can work backwards.

Suppose for Eq1, the answer is one of the numbers, say 3600.

Then (A/5)*(B/2) = 3600, so A*B = 3600*10 = 36000.

Is there a pair in 3x3 grid that multiplies to 36000?

190*189.47 — not integer.

600*60 = 36000, but 60 not in grid.

880*40.9 — no.

252*142.857 — no.

Not working.

Perhaps the directional shapes are not 5 and 2 for Eq1.

Let’s double-check the diamond grid.

In the diamond grid, the top is 5, but in Eq1, the second shape is a top-pointing triangle, so should be 5.

Fourth shape is a right-pointing triangle, so should be 2.

But perhaps in the equation, the shape is not pointing right; let's assume that in Eq1, the fourth shape is a different orientation.

Maybe the "right" in the diamond grid is not the same as the shape's orientation.

I recall that in some versions of this puzzle, the diamond grid numbers are used for the triangular shapes, and the 3x3 for the others, and the key is that the product (A/B)*(C/D) must be integer, and match the answer box.

Let’s try a different equation.

Look at Eq5: ( [shape] ÷ ◇ ) × ( [shape] ÷ [shape] ) = ?

◇ is diamond, which should be 10.

So (A / 10) * (B / C) = D

If C is a directional shape, say 2, then (A*B)/(10*2) = A*B/20 = D

Still complicated.

Perhaps all directional shapes are from the diamond grid, and we can list for each equation what the divisors are.

Let’s define the directional shape values based on orientation:

- Up triangle: 5
- Down triangle: 8
- Left triangle: 6
- Right triangle: 2
- Up-right: 4
- Down-right: 3
- Down-left: 9
- Up-left: 7
- Diamond: 10

Now for each equation, identify the directional shapes and their values.

From the user's description or standard interpretation:

Eq1:
- Second shape: up triangle → 5
- Fourth shape: right triangle → 2
So (A / 5) * (B / 2) = (A*B)/10

Eq2:
- Second shape: up triangle → 5
- Fourth shape: ? In the text, it's "÷ \_" which might be a right triangle or something else. Assume it's right triangle → 2, same as Eq1.

But then same as Eq1, which is unlikely.

In Eq2, the fourth shape might be different.

Perhaps in Eq2, the fourth shape is a down triangle or something.

To save time, let's search for a solution online or think differently.

Another idea: perhaps the "number grids" are to be used as follows: the 3x3 grid is for the non-directional shapes, and the diamond grid is for the directional shapes, and the assignment is that each shape type corresponds to a number, and we need to find which number for which shape by ensuring that the calculations give integer results matching the answer box.

Moreover, since there are 6 equations, and 9 numbers in 3x3, we have to choose 6 pairs or something.

Let’s calculate the product for each equation assuming the directional values, and see what A*B must be.

For Eq1: (A/5)*(B/2) = K => A*B = 10K

K is in answer box, so 10K is 36000,42120, etc.

Now, from the 3x3 grid, find two numbers whose product is 10K for some K in answer box.

List 3x3 numbers: 190,585,329,640,144,303,600,880,252

Compute all pairwise products and see if any equal 10 times an answer box number.

First, answer box: 3600,4212,3760,2569,7482,8360,2470,5080,2424

10 times: 36000,42120,37600,25690,74820,83600,24700,50800,24240

Now compute products of pairs from 3x3:

Start with 190:
190*585 = 111150
190*329 = 62510
190*640 = 121600
190*144 = 27360
190*303 = 57570
190*600 = 114000
190*880 = 167200
190*252 = 47880

None match.

585*329 = 585*300=175500, 585*29=16965, total 192465
585*640 = 374400
too big.

640*144 = 92160
640*303 = 193920
640*600 = 384000
640*880 = 563200
640*252 = 161280

144*303 = 43632
144*600 = 86400
144*880 = 126720
144*252 = 36288

303*600 = 181800
303*880 = 266640
303*252 = 76356

600*880 = 528000
600*252 = 151200

880*252 = 221760

None of these are in the list of 10K.

For example, 144*252 = 36288, close to 36000 but not equal.

36288 vs 36000 — not match.

Perhaps the directional values are different.

Another possibility: in the diamond grid, the number is not for the direction, but for the position, and the shape in the equation matches the shape in the grid.

For example, in the diamond grid, the top position has a triangle pointing up, and number 5, so when you see a up-pointing triangle in the equation, it means 5.

Similarly, for the 3x3 grid, each cell has a number, and perhaps the shape is the cell's border or something, but that's vague.

Perhaps the "shapes" in the equations are the same as the outlines of the cells in the grids, but the grids have numbers, so for the 3x3 grid, the number is associated with the cell, and for the diamond, with the arm.

I think I found a better way.

Let’s look at the first equation: ( 190 ÷ 5 ) × ( ? ÷ 2 ) = ?

In the user's message, for Eq1, it's written as "( 190 ÷ 5 ) × ( _ ÷ _ ) = " but in the image, the 190 is already filled in for the first shape.

In the user's text: "1. ( 190 ÷ 5 ) × ( _ ÷ _ ) = " — oh! So for Eq1, the first shape is already given as 190, and the second as 5.

So 190 is the number for that shape, and 5 is for the up-triangle.

So for Eq1: (190 ÷ 5) × (A ÷ B) = C

190 ÷ 5 = 38

So 38 * (A / B) = C

A and B are shapes, B is a directional shape, so B is from diamond grid, A is from 3x3 grid.

B is the fourth shape, which is a right-pointing triangle, so B=2.

So 38 * (A / 2) = C => 19 * A = C

So C = 19 * A

A is from 3x3 grid: 585,329,640,144,303,600,880,252 (since 190 is used)

Compute 19*A for each:

19*585 = 19*500=9500, 19*85=1615, total 11115 — not in answer box

19*329 = 19*300=5700, 19*29=551, total 6251 — not in box

19*640 = 12160 — not in box

19*144 = 2736 — not in box

19*303 = 5757 — not in box

19*600 = 11400 — not in box

19*880 = 16720 — not in box

19*252 = 4788 — not in box

None match the answer box numbers.

But 19*190 = 3610, close to 3600, but 190 is already used.

Perhaps B is not 2.

In Eq1, the fourth shape might not be right-pointing.

In the user's text, for Eq1, it's "( 190 ÷ 5 ) × ( _ ÷ _ ) = " and the last shape is described as "÷ >" which might be a right-pointing triangle, but perhaps it's down or something.

Maybe " > " means right, but in some fonts, it might be different.

Another idea: perhaps the number 5 is not for the up-triangle, but for the shape itself, and in the diamond grid, the number 5 is at the top, but the shape is the triangle, so when you see that shape, it's 5.

But in Eq1, the second shape is the up-triangle, so 5, and it's given as 5 in the equation? In the user's text, it's "÷ 5" for the second shape, so yes, it's given as 5.

In Eq1: "( 190 ÷ 5 ) × ( _ ÷ _ ) = " so the 5 is already filled in, so for that shape, it's 5.

Similarly, for the fourth shape, it's blank, so we need to find what number it is.

But the fourth shape is a directional shape, so it should be from the diamond grid.

Perhaps for the fourth shape, it's not 2; maybe it's a different orientation.

Let's assume that in Eq1, the fourth shape is a down-pointing triangle, so 8.

Then (190 / 5) * (A / 8) = 38 * (A/8) = (38/8)*A = (19/4)*A

So C = (19/4)*A, so A must be divisible by 4, and C integer.

A from 3x3: 585 odd, 329 odd, 640 div by 4? 640/4=160, yes. 144/4=36, yes. 303 odd, 600/4=150, yes. 880/4=220, yes. 252/4=63, yes.

So A could be 640,144,600,880,252

Then C = (19/4)*A

For A=640, C=19*160=3040 — not in answer box

A=144, C=19*36=684 — not in box

A=600, C=19*150=2850 — not in box

A=880, C=19*220=4180 — not in box

A=252, C=19*63=1197 — not in box

Still not matching.

Perhaps the first shape is not 190 for that shape; in the user's text, it's "1. ( 190 ÷ 5 ) × ( _ ÷ _ ) = " so 190 is given for the first shape, so it's fixed.

Unless 190 is not the number, but the shape is labeled 190, but that doesn't make sense.

I think I need to accept that for Eq1, with 190 and 5 given, and assuming the fourth shape is 2, then C = 19 * A, and none match, so perhaps the answer is 3600, and 19*189.47, not integer.

Another thought: perhaps the division is not exact, but the result is integer, so A must be such that 19*A is in answer box.

Look at answer box: 3600,4212,3760,2569,7482,8360,2470,5080,2424

Divide by 19: 3600/19≈189.47, 4212/19=221.684, 3760/19=197.894, 2569/19=135.210, 7482/19=393.789, 8360/19=440, oh! 8360 / 19 = 440

Is 440 in the 3x3 grid? No, the numbers are 190,585,329,640,144,303,600,880,252 — no 440.

5080/19=267.368, 2424/19=127.578, not integer.

8360/19=440, but 440 not in grid.

Perhaps for a different equation.

Let's try Eq2.

In Eq2: "( _ ÷ 5 ) × ( _ ÷ 2 ) = " assuming the second shape is up-triangle=5, fourth is right-triangle=2.

So (A/5)*(B/2) = C => A*B = 10C

Same as before.

Perhaps in Eq2, the shapes are different.

Maybe the "5" in Eq1 is not from the diamond grid, but from the 3x3, but 5 is not in 3x3.

I recall that in some solutions to this puzzle, the diamond grid numbers are used for the triangular shapes, and the 3x3 for the others, and for Eq1, with 190 and 5 given, and if the fourth shape is 2, then (190/5)*(A/2) = 38 * (A/2) = 19A, and if A=190, but 190 is already used, or A=200, not in grid.

Perhaps the first shape is not 190; in the user's text, it's "1. ( 190 ÷ 5 ) × ( _ ÷ _ ) = " but perhaps 190 is the number for the shape, and it's correct, and we need to find A and B such that 19A = C, and C in answer box, and A in 3x3.

From earlier, 19*440=8360, and 440 not in grid, but 880 is in grid, 19*880=16720, not in box.

19*252=4788, not in box.

Let's list the answer box numbers and see if any is 19 times a number in 3x3.

3x3 numbers: 190,585,329,640,144,303,600,880,252

19*190=3610
19*585=11115
19*329=6251
19*640=12160
19*144=2736
19*303=5757
19*600=11400
19*880=16720
19*252=4788

Answer box: 3600,4212,3760,2569,7482,8360,2470,5080,2424

Closest is 3610 vs 3600, difference of 10, perhaps typo, but unlikely.

Perhaps the 5 is not correct; maybe for the up-triangle, it's not 5.

In the diamond grid, the top is 5, but perhaps for the shape in the equation, it's different.

Another idea: perhaps the number in the diamond grid is for the position, and the shape in the equation matches the shape in the grid, but the grid has the number, so for example, the up-triangle shape corresponds to 5, etc.

I think I need to look for the intended solution.

Upon searching my knowledge, I recall that for this puzzle, the directional shapes correspond to the diamond grid numbers, and the other shapes to the 3x3, and for Eq1, with 190 and 5 given, and if the fourth shape is 2, then (190/5)*(A/2) = 38 * (A/2) = 19A, and if A=190, but duplicate, or perhaps A=200, not.

Perhaps the first shape is 190, but 190 is for that shape, and for the third shape, it's another number.

Let's calculate what A must be for C to be in answer box.

From 19A = C, C in {3600,4212,3760,2569,7482,8360,2470,5080,2424}

A = C/19

3600/19≈189.47
4212/19=221.684
3760/19=197.894
2569/19=135.210
7482/19=393.789
8360/19=440
2470/19=130
5080/19=267.368
2424/19=127.578

None are in the 3x3 grid, but 440 is close to 440, and 880 is in grid, but 880/2=440, not helpful.

130 is not in grid, 127.578 not.

Perhaps for Eq1, the fourth shape is not 2, but 8 (down).

Then (190/5)*(A/8) = 38 * (A/8) = 4.75 A

So C = 4.75 A = 19/4 A

So A must be divisible by 4, C = 19* (A/4)

A/4 must be integer, and 19*(A/4) in answer box.

A in 3x3: 640,144,600,880,252 (div by 4)

A/4: 160,36,150,220,63

19*160=3040
19*36=684
19*150=2850
19*220=4180
19*63=1197

None in answer box.

If fourth shape is 6 (left), then (190/5)*(A/6) = 38 * (A/6) = (19/3) A

C = (19/3) A, so A must be div by 3, C integer.

A in 3x3: 585 (5+8+5=18 div3), 144 (1+4+4=9), 600 (6+0+0=6), 880 (8+8+0=16 not div3), 252 (2+5+2=9), 329 (3+2+9=14 not), 303 (3+0+3=6), 640 (6+4+0=10 not), 190 (1+9+0=10 not)

So A could be 585,144,600,303,252

A/3: 195,48,200,101,84

19*195=3705
19*48=912
19*200=3800
19*101=1919
19*84=1596

None in answer box.

If fourth shape is 4 (up-right), then (190/5)*(A/4) = 38 * (A/4) = 9.5 A = 19/2 A

C = (19/2) A, so A must be even, C = 19*(A/2)

A even: 190,640,144,600,880,252

A/2: 95,320,72,300,440,126

19*95=1805
19*320=6080
19*72=1368
19*300=5700
19*440=8360 -- oh! 8360 is in answer box!
19*126=2394

So if A/2 = 440, then A=880, and C=8360

And 880 is in the 3x3 grid.

So for Eq1: (190 ÷ 5) × (880 ÷ 4) = ?

Fourth shape is up-right triangle, which should be 4.

In the diamond grid, up-right is 4, yes.

So (190/5) = 38, (880/4) = 220, 38*220 = let's calculate: 38*200=7600, 38*20=760, total 8360, yes! And 8360 is in answer box.

Perfect.

So for Eq1, the fourth shape is the up-right triangle, corresponding to 4.

In the user's text, for Eq1, it's "÷ >" which might be interpreted as right, but perhaps in the image, it's up-right.

Anyway, we have it.

So Eq1: (190 ÷ 5) × (880 ÷ 4) = 38 × 220 = 8360

So answer for Eq1 is 8360.

Now, shapes used: first shape: 190 (from 3x3), second: 5 (up-triangle), third: 880 (from 3x3), fourth: 4 (up-right triangle)

Now Eq2: "( _ ÷ 5 ) × ( _ ÷ 2 ) = "

Second shape is up-triangle=5, fourth shape is right-triangle=2 (assuming).

So (A / 5) * (B / 2) = C

A and B from remaining 3x3 numbers: 585,329,640,144,303,600,252 (since 190 and 880 used)

C in answer box, not 8360.

So (A*B)/(10) = C, so A*B = 10C

Possible C: 3600,4212,3760,2569,7482,2470,5080,2424 (exclude 8360)

10C: 36000,42120,37600,25690,74820,24700,50800,24240

Now find A,B from remaining that multiply to one of these.

Try A=600, B=60, not in grid.

A=640, B=56.25, not.

Compute products:

600*60=36000, but 60 not in grid.

640*56.25 no.

144*250=36000, 250 not in grid.

252*142.857 no.

303*118.8 no.

Perhaps A=600, B=60 not, but 600*60=36000, and 60 not available.

Another pair: 640*56.25 no.

Let's list possible.

Note that 36000 = 600*60, but 60 not in grid.

42120 = ? 600*70.2, not.

37600 = 640*58.75, not.

25690 = 303*84.78, not.

74820 = 600*124.7, not.

24700 = 600*41.166, not.

50800 = 640*79.375, not.

24240 = 600*40.4, not.

Perhaps with other numbers.

Try A=585, B=64.1, not.

Maybe the fourth shape is not 2.

In Eq2, the fourth shape might be different.

From the pattern, in Eq2, it might be down or something.

Assume that for Eq2, the fourth shape is 8 (down).

Then (A/5)*(B/8) = C => A*B = 40C

C in answer box, 40C: 144000,168480, etc, too big, since max A*B=880*640=563200, but 40*8360=334400, possible, but 8360 used.

40*3600=144000, is there A*B=144000? 600*240, not in grid. 640*225, not. 880*163.6, not.

Not likely.

Perhaps for Eq2, the second shape is not 5; but in the user's text, it's "÷ 5" for the second shape? In Eq2, it's "( _ ÷ 5 ) × ( _ ÷ _ ) = " so yes, second shape is 5.

Unless in Eq2, the second shape is different, but the user wrote "÷ 5", so probably 5.

Perhaps "5" is for the shape, but in Eq2, it's a different shape.

I think in Eq2, the second shape is still up-triangle, so 5.

Let's look at the third shape in Eq2.

Perhaps we can use the fact that the same shape always has the same number.

For example, the up-triangle is always 5.

In Eq2, fourth shape might be right-triangle=2.

Then (A/5)*(B/2) = C

With A,B from remaining: 585,329,640,144,303,600,252

Try A=600, B=60, not.

A=640, B=56.25, not.

A=144, B=250, not.

A=252, B=142.857, not.

A=303, B=118.8, not.

A=329, B=109.42, not.

A=585, B=61.538, not.

None work.

Perhaps B is not from 3x3; in the equation, the third shape is non-directional, so from 3x3, fourth is directional, from diamond.

In Eq2, the fourth shape might be 3 (down-right).

Then (A/5)*(B/3) = C => A*B = 15C

15*3600=54000, is there A*B=54000? 600*90, not. 640*84.375, not. 880*61.36, not.

15*4212=63180, 640*98.718, not.

Not working.

Another idea: in Eq2, the first shape might be the same as in Eq1 or something.

Perhaps for Eq2, the fourth shape is 2, but A and B are chosen so that A*B/10 = C, and C in box.

Let's calculate A*B for pairs and see if divisible by 10 and quotient in box.

Take A=600, B=60, not.

A=640, B=56.25, not.

A=144, B=250, not.

A=252, B=142.857, not.

A=303, B=118.8, not.

A=329, B=109.42, not.

A=585, B=61.538, not.

Try A=600, B=60 not, but 600*60=36000, and 36000/10=3600, and 3600 is in answer box.

But 60 not in grid.

Unless B is 60, but not available.

Perhaps B is 6, but 6 is from diamond grid, and B is the third shape, which is non-directional, so should be from 3x3.

I think I need to continue with the successful approach.

For Eq1, we have answer 8360.

Now for Eq2: let's assume the fourth shape is 2 (right-triangle).

Then (A/5)*(B/2) = C

Suppose C=3600, then A*B=36000

Is there A,B in remaining 3x3 that multiply to 36000?

Remaining: 585,329,640,144,303,600,252

600*60=36000, but 60 not in grid.

640*56.25 not.

144*250 not.

252*142.857 not.

303*118.8 not.

329*109.42 not.

585*61.538 not.

No.

C=2424, A*B=24240

600*40.4 not.

640*37.875 not.

144*168.333 not.

252*96.19 not.

303*80 not, 303*80=24240, and 80 not in grid.

303*80=24240, but 80 not available.

C=2470, A*B=24700

600*41.166 not.

640*38.593 not.

144*171.527 not.

252*98.015 not.

303*81.518 not.

329*75.076 not.

585*42.222 not.

Not working.

Perhaps for Eq2, the second shape is not 5; but in the user's text, it's "÷ 5", so probably it is.

Unless in Eq2, the "5" is for a different shape, but the shape is the same as in Eq1 for the second position, which is up-triangle, so should be 5.

Perhaps the number 5 is assigned to the shape, and it's correct, but for Eq2, the fourth shape is different.

Let's look at Eq3.

Eq3: "( _ ÷ _ ) × ( _ ÷ _ ) = " no numbers given.

This is hard.

Perhaps from the answer box, and the calculations, we can find.

Another thought: in the diamond grid, the center is 10, and in Eq5, there is a diamond shape, so likely 10.

For example, in Eq5: "( _ ÷ ◇ ) × ( _ ÷ _ ) = " so (A / 10) * (B / C) = D

If C is 2, then (A*B)/(20) = D

etc.

Perhaps start with Eq5.

But let's use the fact that for Eq1, we have 8360, and shapes used: 190,5,880,4

So removed from 3x3: 190,880

From diamond: 5,4

Remaining 3x3: 585,329,640,144,303,600,252

Remaining diamond: 7,6,10,2,3,9,8 (since 5,4 used)

Diamond has 9 numbers: 5,7,4,6,10,2,9,3,8 — so used 5,4, so remaining 7,6,10,2,3,9,8

Now for Eq2: "( A ÷ 5 ) × ( B ÷ C ) = D " but second shape is up-triangle, which is 5, but 5 is already used, and each shape has only one match, so probably the up-triangle is always 5, so it can be reused? The problem says "each shape has only one match", but it doesn't say that the number can't be reused; it says "each shape has only one match", meaning that for a given shape type, it corresponds to one number, but the same number can be used for different instances of the same shape.

In other words, the mapping is from shape type to number, not from instance to number.

So the up-triangle shape always corresponds to 5, so in every equation, when you see an up-triangle, it's 5.

Similarly for others.

So for Eq2, second shape is up-triangle=5, fourth shape is say right-triangle=2.

Then (A/5)*(B/2) = C

A and B from remaining 3x3: 585,329,640,144,303,600,252

C in answer box, not 8360.

So A*B = 10C

Try to find A,B such that A*B is 10 times an answer box number.

For example, if C=3600, A*B=36000

Is 36000 achievable? 600*60, but 60 not in grid.

640*56.25 not.

144*250 not.

252*142.857 not.

303*118.8 not.

329*109.42 not.

585*61.538 not.

Next, C=2424, A*B=24240

303*80=24240, but 80 not in grid.

600*40.4 not.

640*37.875 not.

144*168.333 not.

252*167.142 not.

303*139.009 not.

329*128.024 not.

585*72 not, 585*72=42120? 585*70=40950, 585*2=1170, total 42120, yes!

585*72=42120, but 72 not in grid.

72 is not in 3x3 grid.

But 72 is not available.

Unless B is 72, but not.

Perhaps for Eq2, the fourth shape is not 2, but 72 is not a diamond number.

Diamond numbers are single digit.

So not.

Another pair: 600*70.2 not.

Let's try C=7482, A*B=74820

640*116.906 not.

600*124.7 not.

144*519.583 not.

252*296.904 not.

303*246.93 not.

329*227.416 not.

585*127.897 not.

Not working.

Perhaps for Eq2, the first shape is 600, and fourth shape is 2, then (600/5)*(B/2) = 120 * (B/2) = 60 B = C

So C = 60 B

B from remaining 3x3: 585,329,640,144,303,252 (600 used for A)

60*585=35100 not in box

64*252=16128 not

Not.

A=144, (144/5)*(B/2) = 28.8 * (B/2) = 14.4 B = C

C must be integer, so B must be such that 14.4B integer, so B div by 5, since 14.4=144/10, so B must be div by 5 for C integer.

B in remaining: 585 (div5), 329 not, 640 div5, 303 not, 600 div5, 252 not.

So B=585,640,600

C=14.4*585=8424 not in box

14.4*600=8640 not

Not.

A=252, (252/5)*(B/2) = 50.4 * (B/2) = 25.2 B = C

B must be such that 25.2B integer, 25.2=252/10, so B div by 5.

B=585,640,600

A=303, (303/5)*(B/2) = 60.6 * (B/2) = 30.3 B = C

B div by 10 for C integer? 30.3=303/10, so B div by 10.

B in remaining: 640,600 (since 190,880 used, and 640,600 div by 10)
