Understanding Percentages

A percentage is a way of expressing a number as a fraction of 100. It is denoted by the symbol "%". For example, 50% means 50 out of 100, or half of the total.

Common Percentage Calculations

Finding a percentage of a number: To find X% of Y, multiply Y by (X/100).

Example: What is 25% of 200?
25% of 200 = (25/100) × 200 = 0.25 × 200 = 50

Finding what percentage one number is of another: To find what percentage X is of Y, divide X by Y and multiply by 100.

Example: 50 is what percentage of 200?
50 is (50/200) × 100 = 0.25 × 100 = 25% of 200

Finding percentage change: To find the percentage change from X to Y, calculate (Y - X) / X × 100.

Example: What is the percentage change from 50 to 75?
[(75 - 50) / 50] × 100 = [25 / 50] × 100 = 0.5 × 100 = 50% increase

Increasing by a percentage: To increase X by Y%, multiply X by (1 + Y/100).

Example: 50 increased by 30%
50 × (1 + 30/100) = 50 × 1.3 = 65

Decreasing by a percentage: To decrease X by Y%, multiply X by (1 - Y/100).

Example: 50 decreased by 30%
50 × (1 - 30/100) = 50 × 0.7 = 35
Quick Tip: To find 10% of a number, simply move the decimal point one place to the left. To find 1%, move it two places left.
