What Is a Percentage?

A percentage is a way to express a number as a fraction of 100. The word 'percent' comes from the Latin 'per centum,' meaning 'by the hundred.' For example, 50% means 50 out of every 100, or one half. Percentages are used to compare values, track changes over time, and express proportions.
