What are fractions, decimals and percentages?

A fraction represents a part of a whole, such as 1/4 (one quarter). A decimal expresses the fraction in base-10 form, such as 1/4 = 0.25. A percentage is a fraction with a denominator of 100, such as 1/4 = 25%. They convert to one another: fraction → decimal is numerator ÷ denominator; decimal → percentage is decimal × 100.

How to convert quickly

  1. Fraction to decimal: divide the numerator by the denominator, e.g. 3/4 = 3 ÷ 4 = 0.75
  2. Decimal to percentage: multiply by 100, e.g. 0.75 × 100 = 75%
  3. Percentage to fraction: divide by 100 and simplify, e.g. 25% = 25/100 = 1/4
  4. For repeating decimals (e.g. 1/3 = 0.333…), use the fraction calculator above for the exact fraction
