Comprehensive Calculator Guide

To turn a decimal into a fraction, write it over 10, 100 or 1,000 according to its decimal places, then simplify. 0.75 is 75/100, or 3/4 in lowest terms. Enter a decimal to get the fraction, the mixed number and the percentage.

How the conversion works

Count the digits after the point: 0.75 has two, so it is 75/100, which reduces by 25 to 3/4. 2.125 has three, so it is 2125/1000 = 17/8, or 2 1/8.

The calculator reads the number exactly as typed, so 0.333 is 333/1000, close to but not equal to 1/3. For a repeating decimal, use its exact fraction: 0.333… = 1/3, 0.666… = 2/3.

How to Use

  1. 01Enter the decimal, such as 0.75 or 2.125.
  2. 02Read the fraction in lowest terms.
  3. 03See the mixed number for values above one, and the percentage.

Formula Used

decimal = digits ÷ 10ⁿ (n = decimal places), then simplify
