About the Fraction Simplifier

The AlarmDaddy Fraction Simplifier reduces any fraction to its lowest terms and shows the same value as a decimal, a mixed number and a percentage. Enter a numerator and denominator to simplify results like 18/24 down to 3/4 in one step.

It divides both parts by their greatest common factor to reach lowest terms, keeps the denominator positive, and converts improper fractions into a whole-number-and-fraction mixed form. Handy for maths homework, recipes and measurements.

How to use this calculator

  1. 1Enter the numerator (top number).
  2. 2Enter the denominator (bottom number).
  3. 3Read the simplified fraction, decimal, mixed number and percentage.

The formula

Divide numerator and denominator by their GCF to reach lowest terms.

A fraction is in lowest terms when the numerator and denominator share no common factor other than 1. Dividing both by their greatest common factor reduces it. The decimal is numerator ÷ denominator, and the percentage is that decimal times 100.
