What is a percentage ?

A percentage is a way to express a number as a fraction of 100. It is commonly used to express a proportion or ratio of a quantity in relation to the whole. For example, 20% represents 20 parts out of 100, or 20/100. It can also be written as a decimal or a fraction, with 100% equivalent to 1 or 1/1.

Percentages are used in many different fields, including mathematics, finance, and statistics, to express relative proportions and make comparisons easier. For example, when comparing the growth of two investments, it can be easier to see which one has grown more when expressed as a percentage increase. Additionally, percentages can also be used to calculate discounts, taxes, and other types of assessments. In a more general sense, percentages allow us to make meaningful comparisons between quantities of different scale and express them in a common unit, which is why they are so widely used in various fields and contexts.

Percentage formula

The formula for converting a number to a percentage is:

Percentage = (Number ÷ Total) × 100


For example, if you have 10 apples and you want to express this quantity as a percentage of a total of 100 apples, you would use the following formula:

Percentage = (10 ÷ 100) × 100 = 10%
