The Formula for Calculating Percentages
The formula for calculating percentages is: (part / whole) x 100, where “part” is the fraction of the whole that you’re interested in, and “whole” is the total amount. For example, if you want to know what percentage of 100 is 20, you would use the formula (20 / 100) x 100, which gives you 20 percent.
