How to add fractions

With same denominators

Step 1 - you have to write the same denominator for the answer as in the question.

Step 2 - you have to add both numerators for the numerator of the answer.

Step 3 - simplify if needed


With different denominators

Step 1 - find the least common denominator and write it as the denominator.
