25 1/5 - (8 3/4 + 7 1/8)

First, we need to add the two fractions inside the parentheses:

8 3/4 + 7 1/8
= 8 6/8 + 7 1/8
= 15 7/8

Now we can substitute that back into the original expression:

25 1/5 - 15 7/8

To subtract these mixed numbers, we need to convert them to improper fractions:

25 + 1/5 = 25 + 1/5 = 25 1/5 = 126/5
15 + 7/8 = 15 + 7/8 = 15 7/8 = 127/8

Now we can subtract:

126/5 - 127/8
= (1268 - 1275) / (5*8)
= (1008 - 635) / 40
= 373 / 40

So, the final answer is 373/40.
