What is a Percentage?

Percentage is a term that is commonly used in mathematics, finance, and everyday life. The word percentage comes from the Latin word “per centum,” which means “by the hundred.” It is a way of expressing a part of something as a fraction of 100. This fraction represents how much of the whole an amount or value makes up.

In simple terms, percentage can be defined as the portion or share of something in relation to its whole. It is often used to describe changes in quantities over time or to compare different quantities against each other.
