If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
What else can I help you with?
How do you add and subtract dissimilar fractions?
Make the fractions equivalent then subtract
Do you add and subtract like and unlike fractions in the same way?
