What is the percent of 60 is 15

To find the percent of 15 out of 60, you have to divide fifteen by sixty. 
Then, you multiply your answer by 100. (We do this because 100 percent is a exact amount. 100% of sixty is...well, sixty.)

15 / 60 = 0.25

0.25 * 100 = 25 (basically just moving the decimal two places to the right.)

Next, add a percent sign:

25%, is your answer.
