Answer 32

@angelpooh01

Answer 33

why will d be my answer if 24/40 =0.6 is short for 6 so my answer will be 6

Answer 34

We are trying to replace "a" with a variable that would make the equation true. So if 24/40 is 0.6. 9/___ = 0.6? We replaced "a" (or the empty spot) with different inputs to try and get 0.6, if we input 16, we get 0.5625, when rounded you get 0.6. 16 is the closest answer with the given choices.
