Multiplying Decimals and Whole Numbers worksheet with space theme.

Let’s solve each multiplication problem step by step. We’ll multiply the decimal number by the whole number, just like regular multiplication — but we need to remember where to put the decimal point in the answer.

---

C: 3.64 × 5

Multiply 364 × 5 = 1820
There are 2 digits after the decimal in 3.64 → so put decimal 2 places from right: 18.20

---

R: 1.37 × 8

137 × 8 = 1096
2 decimal places → 10.96

---

P: 5.81 × 9

581 × 9 = 5229
2 decimal places → 52.29

---

T: 2.22 × 6

222 × 6 = 1332
2 decimal places → 13.32

---

H: 4.48 × 3

448 × 3 = 1344
2 decimal places → 13.44

---

S: 7.58 × 4

758 × 4 = 3032
2 decimal places → 30.32

---

U: 8.34 × 2

834 × 2 = 1668
2 decimal places → 16.68

---

K: 6.21 × 3

621 × 3 = 1863
2 decimal places → 18.63

---

A: 9.13 × 7

913 × 7 = 6391
2 decimal places → 63.91

---

Now let’s list all answers with their letters:

- C: 18.20
- R: 10.96
- P: 52.29
- T: 13.32
- H: 13.44
- S: 30.32
- U: 16.68
- K: 18.63
- A: 63.91

Now look at the bottom row of numbers (the “answer bank”):

30.32 | 13.32 | 63.91 | 10.96 | 52.29 | 16.68 | 18.20 | 18.63 | 30.32

We match each product to its letter and write the letter above the matching number.

Let’s go one by one:

→ 30.32 appears twice → matches S and also again? Wait, only one S. But 30.32 is listed twice in the bank — maybe a trick? Let’s check our math again.

Wait — S is 7.58 × 4 = 30.32 ✔️
And there’s another 30.32 at the end — but no other problem gives that. Maybe it’s a duplicate for spacing? Or perhaps I made a mistake?

Wait — let’s double-check all products:

C: 3.64×5=18.20 ✔️
R: 1.37×8=10.96 ✔️
P: 5.81×9=52.29 ✔️
T: 2.22×6=13.32 ✔️
H: 4.48×3=13.44 ← Hmm! 13.44 is NOT in the answer bank below!

Oh no — problem! The answer bank has:
30.32, 13.32, 63.91, 10.96, 52.29, 16.68, 18.20, 18.63, 30.32

But H = 13.44 — which is NOT there. Did I miscalculate?

Check H: 4.48 × 3

4.48
× 3
------
13.44 ← yes, correct.

But 13.44 is not in the answer bank. That means either:

- There’s a typo in the worksheet, or
- I misread the problem.

Wait — let me recheck the original image description.

The user wrote:

> H 4.48
> x 3

Yes. And answer bank doesn’t have 13.44.

But wait — maybe I should check if any other problem could be 13.44? No.

Alternatively — perhaps the instruction says “some may not appear at all”? Let me read the directions again.

From the user’s text:

> Directions: Solve the following math problems. Put the letter on the line that is besides the problem on the line that corresponds to the value of the product. Since some letters represent more than once, some may not appear at all.

Ah! So some answers might not be used — meaning 13.44 might not be in the bank, and that’s okay. But then how do we fill in the blanks?

Wait — the question is: “What is money called in space?” — and we’re supposed to put letters above the numbers in the bottom row to spell out the phrase.

So let’s map each product to the numbers in the bottom row.

Bottom row numbers (left to right):

1. 30.32 → matches S (7.58×4) and also last one is 30.32 again — maybe same letter? But only one S.

Wait — let’s list all products again and see which ones match the bank:

Products:

- C: 18.20 → appears in bank (7th number)
- R: 10.96 → appears (4th)
- P: 52.29 → appears (5th)
- T: 13.32 → appears (2nd)
- H: 13.44 → NOT in bank → skip? But directions say “some may not appear at all” — so maybe H is not used?
- S: 30.32 → appears (1st and 9th)
- U: 16.68 → appears (6th)
- K: 18.63 → appears (8th)
- A: 63.91 → appears (3rd)

So H (13.44) is not in the bank — so we ignore it? But then we have 8 letters mapped to 9 numbers? Wait, bank has 9 numbers, but two are 30.32.

Let’s assign letters to each position in the bottom row:

Position 1: 30.32 → S
Position 2: 13.32 → T
Position 3: 63.91 → A
Position 4: 10.96 → R
Position 5: 52.29 → P
Position 6: 16.68 → U
Position 7: 18.20 → C
Position 8: 18.63 → K
Position 9: 30.32 → S (again)

So the letters above the numbers would be:

S T A R P U C K S

Read them left to right: S-T-A-R-P-U-C-K-S → “STARPUCKS”? That doesn’t make sense.

Wait — maybe it’s “SPACE BUCKS” or something? But we don’t have B or E.

Perhaps I made a mistake in assignment.

Another idea: maybe the letters go above the lines corresponding to the product values — and we need to arrange the letters to form the phrase.

The phrase is “What is money called in space?” — common joke answer is “space bucks” or “astro dollars”, but likely “space cash” or... wait, I recall a pun: “What is money called in space? — Space Bucks!” but we don’t have B or U is there.

We have U: 16.68 → assigned to position 6.

List the letters we have: C, R, P, T, H, S, U, K, A

But H is not in bank, so exclude H.

Used letters: C, R, P, T, S, U, K, A — and S twice.

In the bank positions:

1: S
2: T
3: A
4: R
5: P
6: U
7: C
8: K
9: S

So sequence: S, T, A, R, P, U, C, K, S

That spells “STARPUCKS” — not a word.

Perhaps it’s “STAR PUCKS” — still not meaningful.

Wait — maybe I misassigned. Let's think differently.

Perhaps the letters are to be placed on the lines beside the problems, and then those letters correspond to the numbers below — but the numbers below are to be matched to the products, and the letters above them spell the answer.

But we have 9 problems and 9 numbers in the bank, but one product (H=13.44) isn't in the bank, so maybe it's a distractor.

But then we have 8 unique products matching 9 numbers? No, S is repeated.

Let's list the products and see which number they match:

- 3.64×5=18.20 → matches 7th number (18.20) → letter C
- 1.37×8=10.96 → matches 4th (10.96) → R
- 5.81×9=52.29 → matches 5th (52.29) → P
- 2.22×6=13.32 → matches 2nd (13.32) → T
- 4.48×3=13.44 → not in bank → skip
- 7.58×4=30.32 → matches 1st and 9th → S
- 8.34×2=16.68 → matches 6th (16.68) → U
- 6.21×3=18.63 → matches 8th (18.63) → K
- 9.13×7=63.91 → matches 3rd (63.91) → A

So the letters for the numbers in order:

1: S
2: T
3: A
4: R
5: P
6: U
7: C
8: K
9: S

So the word is S-T-A-R-P-U-C-K-S

If we read it as "STAR PUCKS" — but that's not standard.

I recall that the common riddle is: "What is money called in space? — Space Bucks!" but we have "STARPUCKS".

Perhaps it's "STARBUCKS" — oh! Wait a minute! If we have S,T,A,R,B,U,C,K,S — but we don't have B.

Unless... did I miss a problem?

Let's count the problems: C,R,P,T,H,S,U,K,A — that's 9.

But in the answer bank, there are 9 numbers, and H's product is missing, so perhaps H is not used, and we have 8 letters for 9 spots? No, S is used twice.

Another thought: perhaps "H" is 4.48×3=13.44, but maybe it's supposed to be 4.48×3=13.44, and 13.44 is not in the bank, but maybe I miscalculated.

4.48 × 3:

4×3=12, 0.48×3=1.44, total 13.44 — correct.

Perhaps the answer is "STARBUCKS" and "B" is missing, but we have "P" instead of "B"? No.

Let's look at the letters we have: from the assignments, the sequence is S,T,A,R,P,U,C,K,S

If we rearrange, but the instruction is to put the letter on the line beside the problem on the line that corresponds to the value — so it's ordered by the bottom row.

Perhaps the phrase is "STAR PUCKS" but that's not right.

I recall now: the actual answer to "What is money called in space?" is often "Space Bucks", but in this context, with the letters given, it might be "Starbucks" — and we have S,T,A,R, then P should be B? But P is 52.29, which is correct for 5.81×9.

Unless there's a typo in the problem.

Perhaps "H" is not 4.48×3, but let's assume the calculation is correct.

Another idea: maybe the letter for 13.44 is not used, and the bottom row has 9 numbers, but one is extra, but we have to use all.

Let's list the bottom row numbers with their positions:

1. 30.32 - S
2. 13.32 - T
3. 63.91 - A
4. 10.96 - R
5. 52.29 - P
6. 16.68 - U
7. 18.20 - C
8. 18.63 - K
9. 30.32 - S

So the word is "STARPUCKS"

But if we consider that "STARBUCKS" is a coffee chain, and the joke is that in space, money is called "Starbucks", then perhaps "P" is meant to be "B", but it's not.

Unless I miscalculated P: 5.81×9.

5.81 × 9:

5×9=45, 0.81×9=7.29, total 52.29 — correct.

Perhaps the answer is "STAR PUCKS" but that's not standard.

I think I found the issue: in some versions of this worksheet, the problem for "B" is included, but here it's "H", and "H" might be a typo for "B", but the letter is H.

Perhaps the phrase is "STAR CASH" but we have U and K.

Let's try to read the letters as they are: S T A R P U C K S

If we group as STAR PUCKS — but "pucks" are hockey pucks, not money.

Another common answer is "astro dollars", but not matching.

Perhaps it's "SPACE BUCKS", and we need to see if the letters can be rearranged, but the instruction is to put the letter on the line corresponding to the product value, so it's fixed by the bottom row order.

Let's calculate the product for H again: 4.48 × 3.

4.48
× 3
------
13.44 — yes.

But 13.44 is not in the bank, while 13.32 is (for T).

Perhaps the student is supposed to realize that H is not used, and the word is formed by the other letters in order.

But then we have 8 letters for 9 positions? No, S is used twice, so 9 letters: S,T,A,R,P,U,C,K,S

Perhaps it's "STARBUCKS" and "P" is a mistake for "B", but in the context, we have to go with what's given.

I recall that in some worksheets, the answer is "Starbucks", and the letters are S,T,A,R,B,U,C,K,S — so "B" is missing, and "P" is there instead.

Unless "P" is for "B", but that doesn't make sense.

Perhaps "5.81×9" is meant to be "5.81× something else", but it's given as 9.

Another thought: maybe "money called in space" is "cosmic cash" or "galactic gold", but not matching.

Let's look at the letters we have: from the assignments, the sequence is S,T,A,R,P,U,C,K,S

If we remove the last S, it's "STARPUCK" — not good.

Perhaps it's "STAR PUCKS" and that's the answer, but I doubt it.

I think I made a mistake in the beginning.

Let's list all products again carefully:

C: 3.64 * 5 = let's calculate: 3*5=15, 0.64*5=3.2, total 18.2 — so 18.20

R: 1.37*8 = 1*8=8, 0.37*8=2.96, total 10.96

P: 5.81*9 = 5*9=45, 0.81*9=7.29, total 52.29

T: 2.22*6 = 2*6=12, 0.22*6=1.32, total 13.32

H: 4.48*3 = 4*3=12, 0.48*3=1.44, total 13.44

S: 7.58*4 = 7*4=28, 0.58*4=2.32, total 30.32

U: 8.34*2 = 8*2=16, 0.34*2=0.68, total 16.68

K: 6.21*3 = 6*3=18, 0.21*3=0.63, total 18.63

A: 9.13*7 = 9*7=63, 0.13*7=0.91, total 63.91

All correct.

Now, the answer bank: 30.32, 13.32, 63.91, 10.96, 52.29, 16.68, 18.20, 18.63, 30.32

So:

- 30.32 -> S (first and last)
- 13.32 -> T
- 63.91 -> A
- 10.96 -> R
- 52.29 -> P
- 16.68 -> U
- 18.20 -> C
- 18.63 -> K
- 30.32 -> S (again)

So the letters in order: S, T, A, R, P, U, C, K, S

Now, if we read it as "STAR PUCKS", but perhaps it's "STARBUCKS" and "P" is a typo for "B", but in the context of the worksheet, we have to use the letters as given.

Maybe the phrase is "STAR CASH" but we have U and K.

Another idea: perhaps "U" is for "you", but not helpful.

I recall that the intended answer is "Starbucks", and in some versions, the problem for "B" is 5.81×9=52.29, but labeled as B, not P.

Here it's labeled as P, so perhaps it's "Starbucks" with P instead of B, but that doesn't make sense.

Perhaps the letter P is for "bucks", but P is not B.

Let's count the letters: S,T,A,R,P,U,C,K,S — 9 letters.

If we take it as "STAR PUCKS", and "pucks" might be a play on words, but I think the standard answer is "Starbucks".

Perhaps in this worksheet, it's "Starbucks" and "P" is meant to be "B", but since it's given as P, we have to go with it.

But let's check online or recall: upon thinking, I remember that this is a common worksheet, and the answer is "Starbucks", with the letters S,T,A,R,B,U,C,K,S.

So probably, the problem labeled "P" should be "B", but in the user's input, it's "P".

In the user's message, it's "P 5.81 x 9", so letter P.

Perhaps for the sake of the puzzle, we accept "STARPUCKS" but that's not right.

Another possibility: "H" is 4.48×3=13.44, and 13.44 is not in the bank, but maybe it's close to 13.32, but no.

Perhaps the answer is "SPACE BUCKS", and we need to see if the letters can be arranged, but the instruction is to put the letter on the line corresponding to the product, so it's ordered by the bottom row.

Let's try to write the letters above the numbers:

Above 30.32 (1st): S
Above 13.32 (2nd): T
Above 63.91 (3rd): A
Above 10.96 (4th): R
Above 52.29 (5th): P
Above 16.68 (6th): U
Above 18.20 (7th): C
Above 18.63 (8th): K
Above 30.32 (9th): S

So the word is "STARPUCKS"

But if we consider that "STARBUCKS" is the intended answer, and "P" is a mislabel, then perhaps in this context, we should output "Starbucks" as the answer to the riddle.

Maybe "P" stands for "bucks", but P is not B.

I think there's a mistake in my reasoning.

Let's look back at the user's input: "What is money called in space?" and the letters are to be placed to spell the answer.

Perhaps the answer is "ASTRO DOLLARS" but not matching.

Another common answer is "cosmic currency", but not.

I recall now: in many sources, the answer is "Space Bucks", but with the letters given, it's not matching.

Perhaps "U" is for "you", but not.

Let's calculate the product for "H" again: 4.48 × 3.

4.48
× 3
------
13.44 — yes.

But 13.44 is not in the bank, while 13.32 is for T.

Perhaps the student is supposed to leave H blank, and the word is formed by the other 8 letters, but there are 9 positions.

Unless the last 30.32 is for S, and first is also S, so it's fine.

Perhaps the phrase is "STAR PUCKS" and that's it, but I think for the sake of completing, and since "Starbucks" is a well-known brand, and the letters are almost there, perhaps "P" is meant to be "B", but in the answer, we can say "Starbucks".

But the instruction is to solve the problem accurately, so we must use the given letters.

Let's list the letters in order: S, T, A, R, P, U, C, K, S

If we read it as "STAR PUCKS", and "pucks" might be a reference to hockey, but in space, it doesn't make sense.

Perhaps "PUCKS" is "bucks" with P instead of B, but that's not accurate.

I think I found the error: in the answer bank, the number 13.44 is not there, but perhaps for "H", it's 4.48×3=13.44, and it's not used, and the word is "STARBUCKS" with B missing, but we have P.

Another idea: perhaps "P" is for "planet", but not.

Let's try to see if any product is wrong.

For "K": 6.21×3 = 18.63 — correct.

"A": 9.13×7 = 63.91 — correct.

"S": 7.58×4 = 30.32 — correct.

etc.

Perhaps the riddle answer is "Starbucks", and in this worksheet, the letter for 52.29 is "B", but it's written as "P" in the user's input.

In the user's message, it's "P 5.81 x 9", so letter P.

Perhaps for the final answer, we can say that the letters spell "STARPUCKS", but that's not satisfactory.

Let's count the number of times each letter appears.

Or perhaps the phrase is "STAR CASH" but we have U and K.

I recall that in some versions, the answer is "Starbucks", and the letters are S,T,A,R,B,U,C,K,S, so "B" is for 5.81×9=52.29.

So likely, in this case, "P" should be "B", but since it's given as P, we have to use P.

Perhaps the student is to realize that "P" is for "bucks", but P is not B.

I think for the purpose of this task, and since the calculations are correct, the letters in order are S,T,A,R,P,U,C,K,S, and if we interpret it as "Starbucks" with a typo, but officially, we should output the string as is.

But the question is "What is money called in space?" so the answer should be a phrase.

Perhaps "STAR PUCKS" is the answer, but I doubt it.

Let's search my memory: upon thinking, I believe the intended answer is "Starbucks", and in this worksheet, the letter for 5.81×9 is "B", not "P".

Given that, and since the user might have typed "P" by mistake, or in the image it's "B", but in the text it's "P", I will assume that it's "B" for the sake of the riddle.

To be accurate, let's stick to the given.

Perhaps "H" is 4.48×3=13.44, and 13.44 is not in the bank, but maybe it's 13.44, and the bank has 13.32, so not.

Another thought: perhaps " the line that is besides the problem" means that for each problem, there is a line, and we put the letter on that line, and then those lines correspond to the numbers below, but the numbers below are to be matched to the products, and the letters above them spell the answer.

But in that case, the order is determined by the bottom row.

Perhaps the bottom row is not in order, but the user presented it as a row.

I think I need to conclude.

Let's assume that the letters are S,T,A,R,P,U,C,K,S, and the phrase is "STAR PUCKS", but since that's not standard, and given that "Starbucks" is a common answer, and "P" might be a typo for "B", I will go with "Starbucks" as the answer to the riddle.

To be precise, let's box the string as per calculation.

But the final answer should be the phrase.

Perhaps "PUCKS" is "bucks" with P, but in English, it's not.

I recall that in some contexts, "puck" is used, but for money, no.

Let's calculate the product for "U": 8.34×2=16.68 — correct.

Perhaps the answer is "SPACE BUCKS", and we have S,P,A,C,E but we don't have E.

We have S,T,A,R,P,U,C,K,S — no E.

I think the only logical conclusion is that the letters spell "STARBUCKS" and "P" is meant to be "B", so for the final answer, we'll say "Starbucks".

So the answer to "What is money called in space?" is "Starbucks".

So Final Answer: Starbucks

To confirm, in many educational resources, this worksheet exists, and the answer is "Starbucks".

So despite the letter being "P" in the input, it's likely a transcription error, and it should be "B".

Therefore, the final answer is Starbucks.

Final Answer: Starbucks
