How It Works
A fraction represents a division. To convert it to a percentage, divide the top number (numerator) by the bottom number (denominator) to get a decimal, then multiply by 100 to express it as a percentage.
The Formula
Percentage = (Numerator ÷ Denominator) × 100
Common Uses
This conversion is commonly needed when working with test scores (e.g. 17/20), survey results, recipes, or any situation where you need to express a proportion as a percentage.
