Find a common denominator for both.
OpenStudy (karatechopper):
what is a common multiple of 4 and 9?
OpenStudy (anonymous):
@karatechopper 36
OpenStudy (karatechopper):
Okay. So we need to multiple 4 by 9 to get 36 and we have to multiply 9 by 4 to get 36. Now do the same to each numerator. Whatever you multiply by the denominator, you multiply to the numerator, the denominator just must be the same.
OpenStudy (anonymous):
So 2 1/36?
