What is the percentage?

A percent is a ratio whose second term is 100. Percent means parts per hundred. The word comes from the Latin phrase per centum, which means per hundred. In mathematics, we use the symbol % for percent or the abbreviation pct.
For example, 12% (read as 'twelve percent') is equal to 12/100, or 3/25, or 0.12.
Percentages are used to express how large or small one quantity is relative to another quantity.
