## What is a percentage?

In mathematics, A percentage is a technique to express a number as a fraction of 100. The sign "%" represents it. For example, if 10 out of 100 students in a class received an A, the percentage of students receiving an A is 10%.

You may use the following formula to determine a percentage: (part/whole) x 100 Equals percentage where "part" is the amount of interest and "whole" is the total or basis from which the percentage is calculated.

For example, if you wish to compute the percentage of students in a class of 50 that received an A, you might use the following formula: (10/50) multiplied by 100 is 20% As a result, 20% of the students

In summary, to calculate the percentage of a quantity, you need to divide the part by the whole and multiply the result by 100.
