See below.

Step-by-step explanation:

To calculate a percentage divide by the part by the whole, You will get a decimal. The decimal becomes a percentage after you multiply by 100. This moves the decimal place two places to the right. So 0.10 becomes 10%.

1. 20 is 50% of 40 since 20/40 = 0.5

2. 8/ 32 = 0.25 so it is 25%

3. 2/40 = 1/20 = 0.05 so it is 5%

4. 100/25 = 4 so it is 400%

5. 3/ 2 = 1.5 so 150%

To find a percentage of a number, multiply the number by the decimal conversion of the percent.

6. 0.15(300) = 45

7. 33/75 = 0.44 so it is 44%

8. 12/18 = 2/3 = 0.66 so it is 66%

9. 0.35(1000) = 350

10. 40 is 20% of what can be solved by remembering that 20* 5 = 100%. So 5*40 = 200. The number is 200.
