A fraction becomes a percent by multiplying by 100
To convert a fraction to a percentage, divide the numerator by the denominator and multiply by 100. 3/4 is 75%. 1/3 is 33.333…%, which displays as 33.33% at two decimal places and is marked as rounded because the decimal repeats.
To convert a percentage back to a fraction, write it over 100 and simplify. 75% is 75/100, which reduces to 3/4. This page does not add, subtract, multiply, or divide fractions beyond that conversion.
