Fraction Conversion FAQ

Answers to the most frequently asked questions about converting fractions to percentages and decimals.

To convert a fraction to a percentage, divide the numerator (top number) by the denominator (bottom number) to get a decimal. Then, multiply that decimal by 100 and add the ‘%’ symbol. For example, 3/4 = 3 ÷ 4 = 0.75, and 0.75 × 100 = 75%.

1/3 as a percentage is approximately 33.33%. This is because 1 divided by 3 equals 0.3333…, and multiplying by 100 gives 33.33…%. It is a repeating decimal.
