Let’s solve each problem step by step. Remember:
“Percent of a number” means you multiply the percent (as a decimal) by the whole number.
To convert a percent to a decimal, divide by 100.
Example: 20% = 20 ÷ 100 = 0.20
---
1. 20% of 300
→ 0.20 × 300 =
60
2. 6% of 400
→ 0.06 × 400 =
24
3. 300% of 50
→ 3.00 × 50 =
150
4. 20% of 500
→ 0.20 × 500 =
100
5. 1% of 20
→ 0.01 × 20 =
0.2
6. 25% of 600
→ 0.25 × 600 =
150
7. 50% of 150
→ 0.50 × 150 =
75
8. 5% of 300
→ 0.05 × 300 =
15
9. 3% of 300
→ 0.03 × 300 =
9
10. 6% of 600
→ 0.06 × 600 =
36
11. 60% of 80
→ 0.60 × 80 =
48
12. 60% of 30
→ 0.60 × 30 =
18
13. 80% of 400
→ 0.80 × 400 =
320
14. 80% of 40
→ 0.80 × 40 =
32
15. 5% of 30
→ 0.05 × 30 =
1.5
16. 75% of 100
→ 0.75 × 100 =
75
17. 60% of 80
→ 0.60 × 80 =
48 *(same as #11)*
18. 60% of 30
→ 0.60 × 30 =
18 *(same as #12)*
19. 40% of 40
→ 0.40 × 40 =
16
20. 40% of 90
→ 0.40 × 90 =
36
