How it works

A percent is “out of 100”. So 35% is 35 over 100. If the percent has decimals, scale both the top and the bottom to remove the decimal, then simplify.

Fraction = (Percentage ÷ 100) and then reduce to lowest terms

Examples. 25% = 25/100 = 1/4. 12.5% = 12.5/100 = 125/1000 = 1/8. 150% = 150/100 = 3/2 which is 1 1/2 as a mixed number.

When this helps

Maths homework and exam prep
Recipes and measurements where fractions are easier to read
Converting between formats for worksheets and reports
Quick checks when comparing ratios

Results are simplified automatically. For mixed numbers over 100%, the whole part is shown as well.
