What is a Percentage?

A percentage (represented by the % symbol) is a way of expressing a number as a fraction of 100. The word comes from the Latin per centum, which literally means "by the hundred."

For example, if you say 25%, it means 25 out of every 100, or $\frac{25}{100}$, which simplifies to $\frac{1}{4}$ or 0.25.
