Easiest of them all
How to add fractions
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.
Step 2 - whatever you multiplied your denominators by to get the least common denominators you multiply the numerators by.
Step 3 - you add both of the new numerators and get your answer.
Step 4 - simplify if needed
Step 1- copy the denominator from the question to the answer denominator.
Step 2- subtract the numerators to,get the answer numerator.
Step 3- simplify if needed
