What is Percentage to Fraction Conversion?

Percentage to fraction conversion turns a percent (%) into a fraction. This is useful for math homework, ratios, probability, discounts, and any time you want a percent written as an exact fraction.

If you want to change percent to a fraction, remember that percent means “per 100.” So you can write a percent as a fraction over 100, then simplify.

This page includes a percentage into fraction calculator approach, a percentage to fraction converter explanation, and a percentage to fraction table calculator for common values.

Percent to Fraction Formula

To convert percent to fraction, write the percent as a number over 100 and reduce to simplest form. If the percent has decimals, first write it as a fraction, then simplify.

Percent to fraction =
fraction = percent / 100

Then simplify the fraction to get percent to a fraction in simplest form.

Simplest form step =
simplified = (percent / 100) ÷ GCF

Divide numerator and denominator by the greatest common factor (GCF).

%
= Percent means “per 100”
100
= Denominator used when converting percent into fraction
GCF
= Greatest common factor (used to simplify)
Example: convert percent to fraction
25% = 25/100 = 1/4

Reduce 25/100 by dividing by 25 to get 1/4.

Example: percent to a fraction in simplest form
12.5% = 12.5/100 = 125/1000 = 1/8

Clear the decimal (×10), then simplify.
