What is a percentage?

A percentage is a number or ratio expressed as a fraction of 100. The word percentage comes from the Latin per centum, meaning "per hundred." Percentages are denoted using the % symbol.

Note: To convert a percentage to a decimal, divide by 100. To convert a decimal to a percentage, multiply by 100. For example, 45% as a decimal is 0.45, and 0.45 as a percentage is 45%.
