Remember the following rules when adding fractions:

Rule #1: Never add denominators

Rule #2: Add only the numerators

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

For example,

1/2 + 6/2 = 7/2

1/2 + 1/3 = ?

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

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

1/2 + 1/3 = 3/6 + 2/6 = 5/6

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,

1/4 + 3/8

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

1/4 + 3/8 = 2/8 + 3/8 = 5/8
