9/-12 is an obvious answer to eliminate as the numerator is not negative and the denominator is not positive. -15/20 simplified is -3/4, so you have to find a similar fraction. This means that D and A are eliminate and leaves you with C as the answer.

-10.5+5.3=-5.2
-5.2+20.2=15
Ur Answer Is 15

Solve for a circle then divide by 2. 8 times 3.14 equal 25.12 divide that by 2 and you get 12.56. Now find the answer to the rectangle 14 times 8 is 112. Now add both answers and get 12.56 + 112 = 124.56.
