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 = 10^d

   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
