Let's solve each problem step by step. To find the
percentage of a number, we use the formula:
$$
\text{Percentage of a number} = \frac{\text{Percentage}}{100} \times \text{Number}
$$
We'll apply this to each question.

1. 40% of 80
$$
\frac{40}{100} \times 80 = 0.4 \times 80 = 32
$$
2. 25% of 100
$$
\frac{25}{100} \times 100 = 0.25 \times 100 = 25
$$
3. 28% of 150
$$
\frac{28}{100} \times 150 = 0.28 \times 150 = 42
$$
4. 65% of 60
$$
\frac{65}{100} \times 60 = 0.65 \times 60 = 39
$$
5. 15% of 40
$$
\frac{15}{100} \times 40 = 0.15 \times 40 = 6
$$
6. 20% of 40
$$
\frac{20}{100} \times 40 = 0.2 \times 40 = 8
$$
7. 70% of 80
$$
\frac{70}{100} \times 80 = 0.7 \times 80 = 56
$$
8. 34% of 100
$$
\frac{34}{100} \times 100 = 0.34 \times 100 = 34
$$
9. 50% of 70
$$
\frac{50}{100} \times 70 = 0.5 \times 70 = 35
$$
10. 75% of 120
$$
\frac{75}{100} \times 120 = 0.75 \times 120 = 90
$$
---
11. 55% of 40
$$
\frac{55}{100} \times 40 = 0.55 \times 40 = 22
$$
12. 10% of 70
$$
\frac{10}{100} \times 70 = 0.1 \times 70 = 7
$$
13. 30% of 30
$$
\frac{30}{100} \times 30 = 0.3 \times 30 = 9
$$
14. 55% of 80
$$
\frac{55}{100} \times 80 = 0.55 \times 80 = 44
$$
15. 85% of 60
$$
\frac{85}{100} \times 60 = 0.85 \times 60 = 51
$$
16. 60% of 50
$$
\frac{60}{100} \times 50 = 0.6 \times 50 = 30
$$
17. 45% of 120
$$
\frac{45}{100} \times 120 = 0.45 \times 120 = 54
$$
18. 75% of 80
$$
\frac{75}{100} \times 80 = 0.75 \times 80 = 60
$$
19. 25% of 100
$$
\frac{25}{100} \times 100 = 0.25 \times 100 = 25
$$
20. 90% of 70
$$
\frac{90}{100} \times 70 = 0.9 \times 70 = 63
