Understanding Percentages

A percentage is a way to express a number as a fraction of 100. It is denoted using the percent sign (%). Percentages are used widely in everyday life - from calculating discounts during shopping to understanding interest rates on loans.

Key Percentage Formulas

Basic Percentage

X% of Y = (X/100) × Y

Example: 20% of 100 = (20/100) × 100 = 20

Percentage Increase

Increase = Original Value × (1 + Percentage/100)

Example: Increase 100 by 20% = 100 × (1 + 20/100) = 120

Percentage Decrease

Decrease = Original Value × (1 - Percentage/100)

Example: Decrease 100 by 20% = 100 × (1 - 20/100) = 80
