Find the LCM of the denominators and multiply both the numerator and denominator by the number which makes the denominator equal to the LCM.For ex-
3/5 + 7/3
LCM =15
3/5*(3)+7/3*(5)
9/15+35/15
44/15-answer

3/15 = 3*5/(15*5) = 15/75----(1)

3/15+ 21/75
= 15/75+21/75 [ from (1)]

=(15+21)/75

=36/75

=(3*12)/(3*25)
=12/25 after cancellation of 3
