Ok, so on this one you need to change your mixed numbers to improper fractions.
R
9 5/8 = 8x9+5= 77/8
1 7/8 = 8x1+7 = 15/8
Now subtract since your denominators are equal.
77/8 - 15/8 = 62/8
Now change back to a mixed number, 8 × 7 = 56 with a remainder of 6.
7 6/8 , simplify 6/8 to 3/4.
Your final answer is 7 3/4. Hope this helps you!
