A percentage is a fraction of 100. The symbol % means "per hundred". For example, 50% means 50 per 100, or half.
To find X% of Y, multiply Y by X/100. For example, 20% of 500 = 500 × (20/100) = 100.
Percentage increase = ((New Value - Old Value) / Old Value) × 100. Shows growth between two values.
Discounts, taxes, tips, interest rates, statistics, grades, and comparing values are common percentage applications.
