Fraction to Percent and Percent to Fraction Calculator
This online calculator can calculate the percentage value for an entered fraction, or the fraction value for an entered percentage.
You can use the calculators below to convert the fraction to the percent and vice versa.
Fraction to Percent
To convert a fraction to a percentage, enter the numerator and denominator of the fraction. The calculator divides the numerator by the denominator, multiplies the result by 100 to obtain the percentage, and formats the result according to the desired precision.
Percent to Fraction
Converting a percentage to a fraction is a bit more complicated if you want a simplified result. Let's take the example of 37.5%.
First, the calculator takes the numerator and denominator (37.5 and 100, respectively) and multiplies both by 10 to eliminate the decimal point and obtain whole numbers: 375 and 1000. Then, the calculator finds the greatest common divisor (GCD) of these two integers. Both integers are then divided by the GCD to simplify the fraction. Here's how to do it with our example:
The GCD of 375 and 1000 is 125. 375 divided by 125 equals 3, and 1000 divided by 125 equals 8. The resulting fraction is 3/8.
