Answer: You multiply each denominator with the other one to make it the same. Then what ever you did to the bottom you do to the top.

Find the LCM (least common multiple) of the denominators, and use that as the denominator for the two fractions.

Ex.

(3)/(4) +(2)/(3)

LCM (3, 4) is 12

(9)/(12) +(8)/(12)

=
(17)/(12)
