First write out your equation.
If the fractions have the same denominators (bottom numbers).
Write out the number as your denominator for your answer
Add the numerators (top numbers) together, then you have a final answer.
Example: 4/6 + 1/6 = 4+1/ 6 = 5/6
If your fractions have different denominators.
Find the lowest common number that but denominators have in common.
Multiple each the denominator by the number needed to get the lowest common number.
Multiple numerators with the number close to their denominatiors.
Example: 1/3 + 1/4.
The lowest common factor is 12.
1 x 4/ 3 x 4 + 1 x 3/ 4 x 3 = 4/12 + 3/12 = 7/12
