Percentages

Percentages are a way of expressing a proportion or a fraction of a whole, where the whole is represented as 100. They are denoted by the symbol "%". Percentages are commonly used to compare parts of a whole or to show changes or proportions over time.

For example, if you scored 80 out of 100 on a test, you can express your score as 80%, indicating that you got 80% of the questions correct. Similarly, if a price increases by 10% from its original value, it means the new price is 110% of the original price.

Percentages are widely used in various contexts, including finance, statistics, mathematics, and everyday life, to represent proportions, rates, and changes in quantities. They provide a convenient way to compare and analyze data and are essential for understanding many aspects of modern life.
