Decimal word problems worksheet for elementary students, themed around baking at Caroline's Bakery.

Let’s solve each problem one by one, step by step. We’ll be careful with decimals and units (like ounces vs pounds) so we don’t make mistakes.

---

Problem 1:

Each batch needs 0.6 cups of flour, and makes 12 donuts.
Caroline is making 5 batches.

We need to find how many cups of sugar she needs? Wait — the problem says “flour” in the first sentence but asks for “sugar”. That might be a typo. Let’s check again:

> “Each batch of donuts mix needs 0.6 cups of flour... If Caroline is making 5 batches of donuts, how many cups of sugar does she need?”

Hmm… it mentions flour but asks for sugar. Since no info about sugar per batch is given, this must be a mistake — probably meant to say “flour” instead of “sugar”.

Assuming it’s a typo and they mean flour:

→ 1 batch = 0.6 cups
→ 5 batches = 0.6 × 5 = 3.0 cups

✔ So if it’s flour, answer is 3 cups.

But since the question says “sugar”, and there’s no data on sugar per batch, maybe we’re supposed to assume sugar = flour? Or perhaps it’s an error. Given context, I think it’s safe to assume they meant flour.

Wait — let’s look at Problem 2: it talks about sugar sacks. Maybe Problem 1 is also about sugar? But still, no rate given for sugar per batch.

Actually, re-reading: “Each batch of donuts mix needs 0.6 cups of flour...” — then asks for sugar. This is confusing.

Perhaps it’s a trick? Or misprint? In real homework, you’d ask teacher. But since we have to solve, and only flour amount is given, likely typo → should be flour.

So I’ll go with 3 cups (assuming sugar was meant to be flour).

BUT — wait! Let me check if any other problem gives sugar per batch? No. So probably typo.

Alternatively — maybe “donuts mix” includes both flour and sugar, and 0.6 cups is total dry ingredient? Still doesn’t help.

I think safest assumption: it’s a typo, and they want flour.

Answer: 3 cups

Problem 2:

Two sacks of sugar:
- One has 43.19 ounces
- Other has 55.8 ounces

Total sugar = 43.19 + 55.8

Let’s add:

43.19
+55.80 ← write as 55.80 to line up decimals
= 98.99 ounces

✔ Total = 98.99 ounces

Problem 3:

Mini cookies weigh 1.6 ounces each.
Customer wants 2.5 pounds of cookies.

First, convert pounds to ounces because cookie weight is in ounces.

We know: 1 pound = 16 ounces

So 2.5 pounds = 2.5 × 16 = ?

2 × 16 = 32
0.5 × 16 = 8
Total = 32 + 8 = 40 ounces

Now, each cookie is 1.6 ounces.

Number of cookies = total ounces ÷ ounces per cookie
= 40 ÷ 1.6

Let’s calculate:

40 ÷ 1.6 = ?

Multiply numerator and denominator by 10 to eliminate decimal:
400 ÷ 16 = ?

16 × 25 = 400 → so 25

✔ Customer gets 25 cookies

Problem 4:

Strawberry pie prices:
- Full pie = $17.50
- Half-pie = $9.25

She sells:
- 3 full pies
- 5 half-pies

Money from full pies: 3 × 17.50 = ?

3 × 17 = 51
3 × 0.50 = 1.50
Total = 51 + 1.50 = $52.50

Money from half-pies: 5 × 9.25 = ?

5 × 9 = 45
5 × 0.25 = 1.25
Total = 45 + 1.25 = $46.25

Total money = 52.50 + 46.25 = ?

52.50
+46.25
= 98.75

✔ She makes $98.75

Problem 5:

Fudge brick weighs 33.6 oz

A) How much would 3.5 bricks weigh?

Weight = 3.5 × 33.6

Let’s compute:

First, 3 × 33.6 = 100.8
Then, 0.5 × 33.6 = 16.8
Total = 100.8 + 16.8 = 117.6 oz

✔ A) 117.6 ounces

B) If she sells all 3.5 bricks at $7.90 per brick, how much money?

Money = number of bricks × price per brick
= 3.5 × 7.90

Compute:

3 × 7.90 = 23.70
0.5 × 7.90 = 3.95
Total = 23.70 + 3.95 = 27.65

✔ B) $27.65

C) She has 436.8 ounces of fudge. Each brick is 33.6 oz. How many bricks can she make?

Number of bricks = total ounces ÷ ounces per brick
= 436.8 ÷ 33.6

Let’s divide:

To make easier, multiply numerator and denominator by 10:
4368 ÷ 336

Now divide:

336 × 13 = ?

336 × 10 = 3360
336 × 3 = 1008
Total = 3360 + 1008 = 4368 → exactly!

So 4368 ÷ 336 = 13

✔ C) 13 bricks

Now, let’s double-check all answers quickly:

1) 0.6 × 5 = 3 → assuming typo, answer is 3
2) 43.19 + 55.8 = 98.99 ✔️
3) 2.5 lb = 40 oz; 40 ÷ 1.6 = 25 ✔️
4) 3×17.50=52.50; 5×9.25=46.25; total 98.75 ✔️
5A) 3.5×33.6=117.6 ✔️
5B) 3.5×7.90=27.65 ✔️
5C) 436.8÷33.6=13 ✔️

All checks out.

Final Answer:
1) 3 cups
2) 98.99 ounces
3) 25 cookies
4) $98.75
5A) 117.6 ounces
5B) $27.65
5C) 13 bricks
