you make them have like denominators by multiplying so many times that they have the same denominators or you can make them have like denominators by multiplying the two

just change the fration with the smallest denominator and add or subtract the way you always do.
convert at least one of them so that they have the same denominator, then proceed with the addition or subtraction
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
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.
The fastest and surest way to do that is to have a calculator that has a fraction button. (a b/c)
