How to convert FRACTION to PERCENT
To convert a fraction to a percentage, divide the numerator by the denominator and multiply by 100. For example, 3/4 = 0.75 x 100 = 75%. That is the entire formula.

Fractions and percentages are interchangeable ways to express the same proportion, but context determines which is more useful. Fractions are common in cooking, woodworking, and math textbooks. Percentages are standard in finance, statistics, and everyday communication (a 25% discount is clearer to most people than a 1/4 discount). The conversion is particularly helpful when working with test scores, financial ratios, or any situation where a fraction needs to appear in a report or presentation as a percentage.
Enter the numerator
Type the top number of your fraction. For example, for 3/4, enter 3.
Enter the denominator
Type the bottom number. For 3/4, enter 4. The denominator cannot be zero.
Read the percentage
The result (numerator / denominator x 100) appears immediately with a % symbol.
Adjust decimal places
Use the precision setting to control how many decimal places appear in the output (e.g., 66.67% vs 66.6667%).
Frequently asked questions
What is the formula for converting a fraction to a percentage?
Divide the numerator by the denominator, then multiply by 100. Example: 7/8 = 0.875 x 100 = 87.5%.
What is 1/3 as a percentage?
33.333...% (repeating). It is a non-terminating decimal, so percentages derived from thirds are typically rounded to 33.33% or 33.3%.
Can I convert improper fractions (where numerator > denominator)?
Yes. 5/4 = 125%, 7/3 = 233.33%. Values over 100% simply mean the fraction is greater than 1.
What is 2/5 as a percentage?
2 divided by 5 = 0.4, times 100 = 40%.
How does this relate to converting fractions to decimals?
The decimal step is intermediate: fraction to decimal = numerator / denominator; decimal to percent = multiply by 100. This tool does both steps at once.
