About fractions, decimals, and percents
Fractions, decimals, and percents are three ways of writing the same proportion. A fraction is the ratio of two whole numbers, a decimal is the result of dividing them, and a percent is that same number expressed per hundred.
These conversions are pure math and never change — the results on this page are exact, not rounded (except where rounding is explicitly shown).
