Summer Math Mystery Pictures | 5th & 6th Grade Review - Free Printable

Let’s solve each problem one by one, step by step. We’ll check our work carefully so we get the right answers for coloring the mystery picture!

---

Problem 1: Round the decimal to the nearest tenths place: 8.384

- Look at the hundredths digit (the second digit after the decimal): it’s 8.
- Since 8 is 5 or more, we round up the tenths digit (which is 3) → becomes 4.
- So, 8.384 rounded to the nearest tenth = 8.4

✔ Answer: 8.4 → Color: light blue

---

Problem 2: 33 + 5.12

- Line up decimals:
33.00
+ 5.12
= 38.12

✔ Answer: 38.12 → But wait — looking at the grid and color key, this answer isn’t listed directly. Let’s double-check the problem list.

Actually, in the image, Problem #2 says “33 + 5.12” but the answer choices don’t include 38.12. Hmm… maybe there’s a typo? Wait — let’s look again.

Wait — actually, looking back at the worksheet, the problems are numbered, and the first few are:

1. Round 8.384 → 8.4 → light blue
2. 33 + 5.12 → should be 38.12 — but that’s not in the color key. That can’t be right.

Hold on — perhaps I misread. Let me re-express all problems as written in the image:

From the visible part of the worksheet:

> PROBLEM | ANSWER | COLOR
> ---|---|---
> Round the decimal to the nearest tenths place: 8.384 | ? | light blue
> 33 + 5.12 | ? | red
> Convert 1.32 liters to milliliters. | ? | light brown
> 32 | ? | dark blue
> 0.2 | ? | red
> [6 ÷ 2] × 3 | ? | light blue
> 0.132 kilograms to grams. | ? | black
> How many sides does a quadrilateral have? | ? | red
> What digit is in the tenths place: 432.09 | ? | light brown
> (something) × 3) + 5 | ? | black
> Volume of rectangular prism: length 3m, width 4m, height ? m → probably missing info? Wait — next line says “centimeters to meters.” Maybe two separate?

This is getting messy. Let’s go row by row based on what’s clearly visible and matches the colored grid.

Looking at the completed grid, we see numbers like 8.4, 45, 6, 275, 97.15, 10.71, 1.320, 53, etc.

Also, from the color key on the right:

- light blue → 8.4
- red → 38.12? Not matching. Wait — maybe “33 + 5.12” was meant to be something else? Or perhaps it’s “3.3 + 5.12”? No.

Wait — let’s try solving only the ones that match the grid and color key logically.

Actually, let’s use the fact that the grid is already filled out — so we can reverse-engineer some answers.

But since you asked me to solve the problems accurately, let’s do them properly.

Let me list ALL visible problems from the worksheet text:

From the image transcription:

1. Round 8.384 to nearest tenth → 8.4
2. 33 + 5.12 → 38.12
3. Convert 1.32 L to mL → 1.32 × 1000 = 1320 mL
4. 32 → just 32? Probably means leave as is → 32
5. 0.2 → 0.2
6. [6 ÷ 2] × 3 = 3 × 3 = 9
7. 0.132 kg to g → 0.132 × 1000 = 132 g
8. Sides of quadrilateral → 4
9. Digit in tenths place of 432.09 → 0
10. (? × 3) + 5 — incomplete? Maybe “(something)” — skip for now
11. Volume of prism: l=3m, w=4m, h=? — incomplete
12. cm to m — conversion factor? 100 cm = 1 m → so divide by 100
13. Volume of another prism: l=1.1cm, w=1.7cm, h=? — incomplete

This is inconsistent. Perhaps the worksheet has typos or cut-off text.

But looking at the colored grid, common numbers are:

- 8.4 → appears often → matches rounding problem
- 45 → appears often
- 6 → appears often
- 275 → appears
- 97.15 → appears
- 10.71 → appears
- 1.320 → appears
- 53 → appears
- 32 → appears
- 0.2 → appears
- 4 → for quadrilateral
- 132 → for kg to g? But 0.132kg = 132g — yes
- 1320 → for liters to mL

Ah! So likely:

Problem 3: 1.32 liters to milliliters = 1.32 × 1000 = 1320

Problem 7: 0.132 kg to grams = 0.132 × 1000 = 132

But in the grid, we see “1.320” which might be 1.320 — same as 1.32? Or 1320?

In the grid, cells show “1.320” — which is numerically 1.32, but written with three decimals.

Similarly, “1320” would be one thousand three hundred twenty.

Looking at the color key:

For example, “convert 1.32 liters to milliliters” → answer should be 1320 → and in the grid, we see “1.320” — probably a formatting issue; they mean 1320.

Similarly, “0.132 kg to grams” = 132 → and in grid we see “132” sometimes? Actually, in the grid I see “1.320”, “53”, “275”, etc.

Wait — let’s take specific examples from the grid and match to problems.

For instance, in the top-left of the grid, we have:

Row 1: 6, 8.4, 45, 6, 8.4, 45, 6, 8.4, 45, 6

These correspond to answers of various problems.

So let’s assume the problems are designed so that their answers fill the grid.

Let’s solve each problem as intended, even if wording is slightly off.

Here’s a clean list based on standard interpretation:

---

Problem 1: Round 8.384 to nearest tenth

→ Tenths place is 3, hundredths is 8 ≥ 5 → round up → 8.4

Problem 2: 33 + 5.12

→ 33.00 + 5.12 = 38.12 — but this doesn't appear in grid. Maybe it's "3.3 + 5.12"? 3.3 + 5.12 = 8.42 → rounds to 8.4? Not helpful.

Wait — perhaps “33 + 5.12” is a mistake, and it’s supposed to be “3.3 + 5.12” = 8.42 → still not 8.4.

Another idea: maybe “33” is “3.3”? Unlikely.

Perhaps the problem is “3 + 5.12” = 8.12 → no.

Let’s skip and come back.

Problem 3: Convert 1.32 liters to milliliters

→ 1 liter = 1000 mL → 1.32 × 1000 = 1320 mL

In the grid, we see “1.320” — which might be a way of writing 1320 with a decimal point by mistake? Or perhaps it’s 1.320 meaning 1.32, but that doesn’t make sense for mL.

Actually, in the grid, there is a cell with “1.320” and also “1320” — wait, in the bottom rows, I see “1.320” and “53”, “275”, etc.

Looking closely at the image description, in the grid, one cell says “1.320” — which is likely meant to be 1320, but formatted with a decimal.

Similarly, “0.132 kg to grams” = 132 grams — and in grid, we might have “132” or “1.32”.

But in the color key, for “0.132 kilograms to grams” the color is black, and in the grid, black cells have numbers like 4, or 0? Not clear.

Perhaps we should focus on problems that have clear answers matching the grid.

Let’s list the problems that are fully visible and solvable:

From the worksheet:

1. Round 8.384 to nearest tenth → 8.4
2. 33 + 5.12 → 38.12 — but let's calculate: 33 + 5 = 38, plus 0.12 = 38.12 — correct.
3. Convert 1.32 L to mL → 1320
4. 32 → 32 (just the number)
5. 0.2 → 0.2
6. [6 ÷ 2] × 3 = 3 × 3 = 9
7. 0.132 kg to g → 132
8. Sides of quadrilateral → 4
9. Digit in tenths place of 432.09 → the tenths place is the first digit after decimal, which is 0
10. ( ? ) × 3 + 5 — incomplete. Maybe "(4 × 3) + 5" = 12 + 5 = 17? Not in grid.
11. Volume of prism: l=3m, w=4m, h= ? — if h is given elsewhere? The next line says "centimeters to meters" — perhaps two separate problems.
12. Convert cm to m — e.g., 100 cm = 1 m, so to convert, divide by 100. But no specific number given.
13. Volume of prism: l=1.1cm, w=1.7cm, h= ? — incomplete.

This is frustrating. Perhaps the worksheet has errors, or the image is cropped.

But looking at the completed grid, the most frequent numbers are:

- 8.4
- 45
- 6
- 275
- 97.15
- 10.71
- 1.320 (which may be 1320)
- 53
- 32
- 0.2
- 4
- 132 (for kg to g)

Let’s assume that "1.320" in the grid is meant to be 1320 for the liters to mL problem.

Similarly, for "0.132 kg to grams" = 132, and in the grid, we might have "132" — but in the image description, I see "1.320", not "132". In the bottom, there is "1.320", "53", "275", etc.

Perhaps "1.320" is 1.320, which is 1.32, but that doesn't help.

Another approach: let's solve the problems that are clear and match the color key.

From the color key on the right:

- light blue: 8.4
- red: 38.12? Or 4? Let's see.

In the grid, red cells have numbers like 275, 97.15, 10.71, etc.

For example, "how many sides does a quadrilateral have?" = 4 — and in the grid, there are cells with 4, and they are colored red? In the image, some 4's are in red areas.

Similarly, "digit in tenths place of 432.09" = 0 — and 0 might be in light brown cells.

But this is guesswork.

Perhaps the best way is to provide the correct mathematical answers for each problem as stated, even if they don't perfectly match the grid, because the grid might have its own logic.

So let's do that.

Final decision: Solve each problem mathematically correctly.

---

Problem 1: Round 8.384 to nearest tenth

- 8.384
- Tenths digit: 3
- Hundredths digit: 8 ≥ 5, so round up 3 to 4
- Answer: 8.4

Problem 2: 33 + 5.12

- 33.00 + 5.12 = 38.12
- Answer: 38.12

Problem 3: Convert 1.32 liters to milliliters

- 1 L = 1000 mL
- 1.32 × 1000 = 1320
- Answer: 1320

Problem 4: 32

- This is just the number 32
- Answer: 32

Problem 5: 0.2

- Just 0.2
- Answer: 0.2

Problem 6: [6 ÷ 2] × 3

- 6 ÷ 2 = 3
- 3 × 3 = 9
- Answer: 9

Problem 7: 0.132 kilograms to grams

- 1 kg = 1000 g
- 0.132 × 1000 = 132
- Answer: 132

Problem 8: How many sides does a quadrilateral have?

- Quadrilateral means 4-sided polygon
- Answer: 4

Problem 9: What digit is in the tenths place: 432.09

- Number: 432.09
- After decimal: 0 is tenths, 9 is hundredths
- Answer: 0

Problem 10: ( ? ) × 3 + 5 — incomplete. Assume it's "(4 × 3) + 5" = 12 + 5 = 17? But not specified. Skip or assume based on context.

Since it's incomplete, and in the grid we have numbers like 53, 275, etc., perhaps it's a different problem.

Looking back at the image text: "me of the rectangular prism of 3 m, width of 4 m, and a m." — probably "height of ? m" — but not given. Then "centimeters to meters." — perhaps "convert 100 cm to meters" = 1 m.

Then "of the rectangular prism '1 cm, width of 1.7 cm, cm." — incomplete.

This is too ambiguous.

Perhaps for the sake of completing, let's assume the problems that are clear.

But to give a final answer, I need to provide the solutions.

Perhaps the user expects the answers that match the grid, so let's use the grid values.

From the grid, the answers used are:

- 8.4
- 45
- 6
- 275
- 97.15
- 10.71
- 1.320 (assume 1320)
- 53
- 32
- 0.2
- 4
- 132 (but not seen, so perhaps 1.32)

For example, "33 + 5.12" might be a distractor, or perhaps it's "3.3 + 5.12" = 8.42 ≈ 8.4, but not exact.

Another idea: perhaps "33" is "3.3", and "3.3 + 5.12" = 8.42, which rounds to 8.4, but the problem says "solve", not "round".

I think I need to box the answers as per correct math.

So for the problems that are complete:

1. 8.4
2. 38.12
3. 1320
4. 32
5. 0.2
6. 9
7. 132
8. 4
9. 0

For the others, since they are incomplete, I'll omit or assume.

But to match the grid, let's see what numbers are in the grid and assign.

Perhaps the "SUMMER 5TH GRADE MIXED REVIEW #1" has specific problems, and from the image, the first few are:

- Round 8.384 -> 8.4
- 33 + 5.12 -> 38.12
- 1.32 L to mL -> 1320
- 32 -> 32
- 0.2 -> 0.2
- [6÷2]×3 -> 9
- 0.132 kg to g -> 132
- sides of quadrilateral -> 4
- digit in tenths place of 432.09 -> 0
- then "( something ) × 3 + 5" — perhaps "(8 × 3) + 5" = 24 + 5 = 29? Not in grid.
- volume of prism: if l=3, w=4, h=5, then V=60, not in grid.
- cm to m: e.g., 53 cm = 0.53 m, but in grid we have 53, so perhaps "53 cm to m" = 0.53, but grid has 53, so maybe they want the number before conversion.

This is not working.

Let's look at the color key again:

From the image:

COLOR KEY:
- light blue: 8.4
- red: 38.12? Or for "33+5.12" -> 38.12, and in grid, red cells have 275, etc., so not matching.

Perhaps the "ANSWER" column in the worksheet is to be filled, and then matched to color.

For example, for "33 + 5.12" = 38.12, and if 38.12 is not in the color key, then it's a problem.

Unless the color key has "38.12" for red, but in the image, for red, it says "red" for several problems, including "33+5.12", "0.2", "sides of quadrilateral", etc.

In the color key table:

PROBLEM | ANSWER | COLOR
---|---|---
Round 8.384 | ? | light blue
33 + 5.12 | ? | red
1.32 L to mL | ? | light brown
32 | ? | dark blue
0.2 | ? | red
[6÷2]×3 | ? | light blue
0.132 kg to g | ? | black
sides of quadrilateral | ? | red
digit in tenths place 432.09 | ? | light brown
(? × 3) + 5 | ? | black
volume of prism 3m x 4m x ? | ? | dark blue
cm to m | ? | light blue
volume of prism 1.1cm x 1.7cm x ? | ? | white
etc.

And the colors are assigned to the answers.

For example, for "33 + 5.12" = 38.12, and if 38.12 is not in the grid, then perhaps it's a different interpretation.

Perhaps "33" is "3.3", and "3.3 + 5.12" = 8.42, which is close to 8.4, but not exact.

I think I have to conclude with the correct mathematical answers.

So for the sake of providing an answer, I'll list the solutions for the clear problems.

Final Answer for each:

1. 8.4
2. 38.12
3. 1320
4. 32
5. 0.2
6. 9
7. 132
8. 4
9. 0

For the incomplete ones, I'll skip.

But since the grid has specific numbers, and the user might expect those, let's notice that in the grid, "45" appears frequently, and "6", "8.4", etc.

Perhaps "33 + 5.12" is not a problem, or it's "3 + 5.12" = 8.12, not helpful.

Another thought: perhaps "33" is the problem number, and the problem is "5.12" alone, but that doesn't make sense.

I recall that in some worksheets, "33" might mean "3^3" = 27, but 27 not in grid.

Or "3*3" = 9, which is in problem 6.

I think I need to box the answers as per calculation.

So for the response, I'll provide the correct answers for the problems that are fully stated.

Final Answer:
The solutions to the math problems are:
- Rounding 8.384 to the nearest tenth: 8.4
- 33 + 5.12: 38.12
- Converting 1.32 liters to milliliters: 1320
- The number 32: 32
- The number 0.2: 0.2
- [6 ÷ 2] × 3: 9
- Converting 0.132 kilograms to grams: 132
- Number of sides in a quadrilateral: 4
- Digit in the tenths place of 432.09: 0

Note: Some problems in the worksheet appear to be incomplete or may contain typos, so only the fully clear problems are solved here. Use these answers to color your mystery picture according to the color key provided in your worksheet.
