Convert a decimal number into a fraction in lowest terms. Useful for measurements, recipes, and math homework where a fraction is clearer than a decimal. The result is shown both as a reduced fraction and, when the value is more than one, as a mixed number.

How this is calculated

The decimal is written over a power of ten, then reduced by dividing the top and bottom by their greatest common divisor. So 0.375 becomes 375/1000, which reduces to 3/8. Values above one are also shown as a whole number plus a proper fraction.

How to use

  1. Enter a decimal number.
  2. Read the reduced fraction.
  3. Use the mixed-number form when the value is greater than one.

Examples

  • One half: 0.5 = 1/2
  • Three eighths: 0.375 = 3/8
  • Two and a half: 2.5 = 5/2, or 2 1/2

FAQ

How do you turn a decimal into a fraction?
Write the decimal over a power of ten based on its decimal places, then divide the top and bottom by their greatest common divisor. So 0.5 is 5/10, which reduces to 1/2.
What is a mixed number?
A mixed number is a whole number next to a proper fraction, such as 2 1/2, which is another way of writing the improper fraction 5/2.
