Let's solve each problem step by step. The general formula to find a percentage of a number is:
$$
\text{Percentage of a number} = \left( \frac{\text{Percent}}{100} \right) \times \text{Number}
$$
We'll apply this formula to each question.

1. 200% of 24
$$
\frac{200}{100} \times 24 = 2 \times 24 = 48
$$
2. 45% of 80
$$
\frac{45}{100} \times 80 = 0.45 \times 80 = 36
$$
3. 100% of 8
$$
\frac{100}{100} \times 8 = 1 \times 8 = 8
$$
4. 50% of 128
$$
\frac{50}{100} \times 128 = 0.5 \times 128 = 64
$$
5. 300% of 42
$$
\frac{300}{100} \times 42 = 3 \times 42 = 126
$$
6. 100% of 81
$$
1 \times 81 = 81
$$
7. 200% of 10
$$
2 \times 10 = 20
$$
8. 400% of 28
$$
4 \times 28 = 112
$$
9. 150% of 300
$$
1.5 \times 300 = 450
$$
10. 200% of 12
$$
2 \times 12 = 24
$$
11. 250% of 100
$$
2.5 \times 100 = 250
$$
12. 40% of 70
$$
0.4 \times 70 = 28
$$
13. 70% of 600
$$
0.7 \times 600 = 420
$$
14. 200% of 80
$$
2 \times 80 = 160
$$
15. 20% of 220
$$
0.2 \times 220 = 44
$$
16. 100% of 320
$$
1 \times 320 = 320
$$
17. 350% of 80
$$
3.5 \times 80 = 280
$$
18. 300% of 30
$$
3 \times 30 = 90
$$
19. 180% of 180
$$
1.8 \times 180 = 324
$$
20. 30% of 120
$$
0.3 \times 120 = 36
$$
21. 220% of 60
$$
2.2 \times 60 = 132
$$
22. 40% of 20
$$
0.4 \times 20 = 8
$$
23. 40% of 160
$$
0.4 \times 160 = 64
$$
24. 320% of 70
$$
3.2 \times 70 = 224
$$
