Let’s solve each part step by step.
---
Part A: Convert the following fractions to percents.
To convert a fraction to a percent, divide the numerator by the denominator, then multiply by 100.
1) 5/10
→ 5 ÷ 10 = 0.5
→ 0.5 × 100 = 50%
✔ Answer:
50%
2) 3/20
→ 3 ÷ 20 = 0.15
→ 0.15 × 100 = 15%
✔ Answer:
15%
3) 2/5
→ 2 ÷ 5 = 0.4
→ 0.4 × 100 = 40%
✔ Answer:
40%
4) 1/2
→ 1 ÷ 2 = 0.5
→ 0.5 × 100 = 50%
✔ Answer:
50%
5) 33/100
→ Already over 100 → 33%
✔ Answer:
33%
6) 7/8
→ 7 ÷ 8 = 0.875
→ 0.875 × 100 = 87.5%
✔ Answer:
87.5%
7) 8/25
→ 8 ÷ 25 = 0.32
→ 0.32 × 100 = 32%
✔ Answer:
32%
8) 22/100
→ Already over 100 → 22%
✔ Answer:
22%

Part B: Match each fraction with its equivalent percent.
We’ll convert each fraction to a percent and match.
1) 1/2 → 50% → matches
c) 50%
2) 7/10 → 70% → matches
a) 70%
3) 9/25 → 9 ÷ 25 = 0.36 → 36% → matches
b) 36%
So:
- 1 → c
- 2 → a
- 3 → b
