Enter a fraction x/y and a fraction a/b to subtract from the first fraction. The calculator will display the simplified value after subtraction.

## Fraction Subtraction Calculator

The following formula is used to calculate a subtraction of two fractions.

X/Y – A/B = C/D

- Where X/Y is the first fraction
- A/B is the fraction being subtracted from X/Y
- C/D is the new resulting fraction

How to subtract fractions

**First, determine the fractions**Determine the two fractions, x/y and a/b that are to be used in the calculation.

**Next, convert the denominators to like terms**Using the LCM of the denominators, convert the fractions so that the denominators are equal. For example, if the fractions were 1/2 and 1/6, you would want to multiply 1/2 *3 = 3/6.

**Subtract the fractions**Subtract 3/6 – 1/6 = 2/6.

**Simplify the equation**Divide both sides of the fraction by their GCD = 2, so 2/6 / 2/2 = 1/3.

## FAQ

**How do i subtract fractions?**

Subtracting fractions involves converting two fractions so they have matching denominators, and then performing the subtraction on the numerators only after conversion.
