Answer:

C, 9

Explanation:

Start by substituting.
a-10b/c should turn into
2 - 10(1/2) / -(1/3). Then do all the multiplying in the parentheses to get
2-5/-(1/3). Subtract 2-5 to get
-3/-(1/3). 1/3 goes into one three times, so it goes into three nine times. By negating both 1/3 and 3, the nine stays positive, so the answer is 9.
