Fraction Calculator Formula / How It Works

The calculator calculates the common denominator to perform the arithmetic and uses the greatest common divisor to simplify the result.

Formula:GCD (Greatest Common Divisor) used to simplify fractional outcomes.

Example Calculation:

For example, let's look at adding 3/4 and 2/3 together using the fractional operators. By entering these values into the tool, you will get an unsimplified sum of 17/12, which represents the mixed number 1 5/12 and decimal 1.4167 instantly.
