How Percentages Work

Percentage of a number: Multiply the number by the percentage divided by 100. Example: 15% of 200 = 200 x (15/100) = 30.

What percentage: Divide the part by the whole and multiply by 100. Example: 30 is what % of 200? (30/200) x 100 = 15%.

Percentage change: ((New - Old) / Old) x 100. A positive result is an increase; negative is a decrease.
