According to a recent survey, 21 percent of people prefer apples over oranges. Express 21 percent as a decimal.

In order to convert from percentages to decimals, we divide by 100 as the word percent means out of 100. When dividing by 100, all of our digits move two places to the right. 21 divided by 100 is therefore equal to 0.21. This means that 21 percent expressed as a decimal is 0.21.
