What is a Percentage?

A percentage is a way of expressing a number as a fraction of 100. It is represented using the "%" symbol.

For Example

If there are 100 students in a class and 25 of them are girls, then:

25/100 × 100 = 25%

This means that 25% of the students are girls.

How to Calculate a Percentage?

The basic percentage formula is:

Percentage = (Part ÷ Whole) × 100

Example

If a student scores 75 marks out of 100:

(75 ÷ 100) × 100 = 75%

The student's percentage is 75%.
