Let’s solve each problem one by one. We’ll use division since all these problems involve splitting a total amount into equal parts.

Problem 1:
Jessie bought
22.8 pounds of candies.
Each box holds
3.8 pounds.
We need to find how many boxes she used → divide total weight by weight per box.
→ 22.8 ÷ 3.8
To make it easier, multiply both numbers by 10 to remove decimals:
228 ÷ 38 = ?
Let’s divide:
38 × 6 = 228 → So, 228 ÷ 38 = 6
✔ Answer:
6 boxes

Problem 2:
Linda walked
6.3 miles in
1.5 hours.
We want distance covered in
one hour → that’s her speed (miles per hour).
→ Divide total miles by total hours: 6.3 ÷ 1.5
Multiply numerator and denominator by 10 to eliminate decimal:
63 ÷ 15 = ?
15 × 4 = 60 → remainder 3 → so 4 + 3/15 = 4 + 1/5 = 4.2
✔ Answer:
4.2 miles per hour

Problem 3:
Total space used:
84.6 megabytes
Each file uses:
21.15 megabytes
Find number of files → divide total by size per file.
→ 84.6 ÷ 21.15
Multiply both by 100 to eliminate decimals:
8460 ÷ 2115
Let’s simplify:
Divide numerator and denominator by 15:
8460 ÷ 15 = 564
2115 ÷ 15 = 141
Now: 564 ÷ 141
141 × 4 = 564 → exactly!
✔ Answer:
4 files

Problem 4:
Jim made
19.8 gallons of juice.
Each container holds
6.6 gallons.
How many containers? → divide total by capacity per container.
→ 19.8 ÷ 6.6
Multiply both by 10: 198 ÷ 66
66 × 3 = 198 → exactly!
✔ Answer:
3 containers

Problem 5:
Bag weighs
3.3 pounds total.
Each gift weighs
1.65 pounds.
How many gifts? → divide total weight by weight per gift.
→ 3.3 ÷ 1.65
Multiply both by 100: 330 ÷ 165
165 × 2 = 330 → exactly!
✔ Answer:
2 gifts

Final Answer:
1) 6
2) 4.2
3) 4
4) 3
5) 2
