How To Use the Decimal to Fraction Calculator 

Enter in the decimal number to see what the fraction value is. 

How to Convert Decimals to Fractions?

1. Convert the decimal value to a fraction (count how many decimal values there are and add that many zeros to the denominator after 1).

   $$ 1.345 = {1.345 \over 1}$$

   $$ {1.345 \over 1} \times {1000 \over 1000} = {1345 \over 1000} $$

2. Find the greatest common divisor (gcd) of the numerator and denominator.

3. Reduce the fraction by dividing the numerator and denominator by the gcd. 

Decimal to Fraction Conversion Examples

Suppose we want to convert 0.84 to a fraction. 

1. We can rewrite this as 84 / 100 since there are 2 values after the decimal place. 

2. The greatest common divisor is 4. 

3. 84 / 4 = 21 100 / 4 = 25 

Our final answer is 21/25.
