Decimal to Fraction Converter

Convert any decimal number to its simplest fraction form with this free calculator. Enter a decimal and instantly see the equivalent fraction, mixed number, numerator, and denominator.

Converting decimals to fractions is a common task in math, cooking, engineering, and many other fields. Every terminating decimal can be expressed as a fraction by placing the decimal digits over a power of 10, then simplifying.

How to Convert a Decimal to a Fraction:

  1. Count the number of decimal places.
  2. Write the decimal as a fraction with the appropriate power of 10 as the denominator.
  3. Simplify by dividing both numerator and denominator by their greatest common divisor.

For example, 0.375 has 3 decimal places, so it becomes 375/1000. The GCD of 375 and 1000 is 125, so the simplified fraction is 3/8.

Mixed Numbers:

When the decimal is greater than 1 (or less than -1), the result can be written as a mixed number combining a whole number and a proper fraction. For instance, 2.75 = 2 and 3/4.
