Perform the operation(s) and write the answer in simplest form.
( 1/2 + 1/3) / 15/4
a.) 3 1/8
b.) 53/90
c.) 2/9
d.) 8/75

First add the fractions in the parenthesis: 1/2+1/3.. In order to do this find the common denominator, which in this case is 6.  So 3/6+2/6=5/6.  Now you have 5/6/15/4.  Divide the fractions and then simplify to get 2/9.

Hope the explanation helped!
