Fraction to percent formula

Multiply the fraction by 100. The fraction is the numerator over the denominator, so the same step reads: numerator over denominator, multiplied by 100. Whatever that gives is the percent.

The arithmetic is exact. A few results are collected in the table below, where 1/2 is listed as 50%, 3/4 as 75% and 1/8 as 12.5%.

Fractions and their percents

The table pairs fractions you may meet often with the percent each one converts to: 1/4 is 25%, 1/5 is 20%, 1/10 is 10% and 3/2 is 150%. A fraction larger than one, such as 3/2, gives a percent larger than 100.
