1. ### Set up division formula

Put the number of desired items or outcomes over the number of total possible outcomes. If a person makes five out of eight basketball shots, the formula is 5/8 or 5 divided by 8.

The answer to 5 divided by 8 in decimal form is 0.625.

3. ### Multiply by 100

To convert a decimal to a percentage, multiply it by 100. The result of 0.625 multiplied by 100 is 62.5; therefore, a person who makes five out of eight shots has a 62.5 percent success rate.
