### What is Percentage?

Percentage is a way of expressing a fraction of 100, often used to represent a proportion or a rate of change. It is commonly used in a variety of fields, from finance and economics to science and statistics, and is an essential tool for making sense of data and trends.

Percentage changes are particularly useful for comparing changes in values over time or across different groups. For example, if the sales of a company increase by 10% from one year to the next, it means that the sales have increased by one tenth of the initial value.

Overall, percentages are a powerful and versatile tool for analyzing data and communicating information in a clear and concise way.
