Percent to Fraction Calculator

What This Calculator Does

A percent is already a fraction with 100 on the bottom. “75%” literally means 75/100 - so to turn a percent into a fraction, you write it over 100 and simplify. 75/100 reduces to 3/4.

Type a percent and the tool writes it over 100, reduces it to lowest terms, and shows a mixed number for percents above 100.

How to Convert a Percent to a Fraction

1. Write the percent over 100.
2. Simplify by dividing the top and bottom by their greatest common divisor.

For example, $75\% = \frac{75}{100}$, and dividing both by 25 gives $\frac{3}{4}$.

How to Use It

1. Enter a percent (for example, 75 or 12.5).
2. Read the simplified fraction, plus the mixed number when the percent is above 100.

Worked Examples
