How to convert decimal to fraction

  1. Count the number of digits (d) to the right of the decimal point of the decimal number x.

    Example: 2.56 has 2 digits to the right of the decimal point, so d=2.

  2. Calculate the factor (f) for making the decimal number an integer:

    f = 10d

    Example:

    f = 102 = 100

  3. Multiply and divide the decimal number x by the factor f:

    x × f / f  =  y / f

    Example:

    2.56 × 100 / 100 = 256 / 100

  4. Find the greatest common divisor (gcd) of the fraction.

    Example:

    gcd(256,100) = 4

  5. Reduce the fraction by dividing the numerator and denominator by the gcd value:

    Example:

    256 / 100 = (256/4) / (100/4) = 64/25
