To find a percentage of a number, multiply the percentage (divided by 100) by the number.
Example: 25% of 80
(25 ÷ 100) × 80 = 0.25 × 80 = 20
Example: 150% of 40
(150 ÷ 100) × 40 = 1.5 × 40 = 60
To find what percent one number is of another, divide the first number by the second and multiply by 100.
Example: What percent is 15 of 60?
(15 ÷ 60) × 100 = 0.25 × 100 = 25%
Example: What percent is 90 of 60?
(90 ÷ 60) × 100 = 1.5 × 100 = 150%
To find the percentage increase, subtract the original value from the new value, divide by the original value, and multiply by 100.
Example: Increase from 50 to 75
((75 - 50) ÷ 50) × 100 = (25 ÷ 50) × 100 = 0.5 × 100 = 50%
To find the percentage decrease, subtract the new value from the original value, divide by the original value, and multiply by 100.
Example: Decrease from 80 to 60
((80 - 60) ÷ 80) × 100 = (20 ÷ 80) × 100 = 0.25 × 100 = 25%
