Remember the following rules when subtracting fractions:

Rule #1: Never add denominators

Rule #2: Subtract only the numerators

Rule #3: Subtract the numerators only and only if the denominators are the same

For example,

6/2 - 1/2 = 5/2

1/2 - 1/3 = ?

You cannot subtract the numerators because the denominators are not the same

Look for equivalent fractions to make the denominators the same before subtracting the numerators

1/2 - 1/3 = 3/6 - 2/6 = 1/6

If one denominator divide the other denominator, the calculator below will use the highest denominator as the common denominator. That is how I made it because it keeps your calculation simple.

For example,

3/8 - 1/4

4 divide 8, so you can choose 8 as a common denominator

3/8 - 1/4 = 3/8 - 1/4 = 3/8 - 2/8 = 1/8

Also, the calculator will not reduce the answer. I am still working on a calculator that will reduce fractions.Stay tune!
