A 1
B 4/3
C 9
D 12

Answer 1

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.
