that's it,hope this help.
First convert everything into an improper fraction.
7 1/2=15/2
4 1/2= 9/2
5 1/8= 41/8
Now do what is in parentheses
2 and 8 share 8 as their LCD
9/2=36/8
36/8-41/8=-5/8
Now divide.
(15/2)/(-5/8)
(15/2)*(-8/5)
15*-8=-120
5*2=10
-120/10
Now simplify
Divide both by 10
-120/10=-12
10/10=1
-12 is your answer!
