First need to do inside the parentheses.
Rewrite the fractions as improper fractions and so they have common denominators:
4 1/2 = 9/2 = 36/8
5 1/8 = 41/8
Now you have 36/8 - 41/8 = -5/8
The problem is now 7 1/2 / -5/8
Rewrite 7 1/2 as 15/2
The problem is now 15/2 / -5/8
When dividing by a fraction change it to multiplication and flip the fraction over:
15/2 x -8/5
Now multiply the top numbers together and the bottom numbers together:
15/2 x -8/5 = (15 x -8) / (2 x 5) = -120/10 = -12
Answer: -12
