Which number is not equivalent to 40/200

D is NOT equivalent to 40/200 because 40/200= 20% 

We can look at the last 2 and figure out the answer very quickly. We know it can't be 20% and 40% but it can be 1/5 and 4/20 because it simplifies. So knowing that all we need to do is 40/200 and then we will have the answer. 40/200=0.2 which is equivalent to 20%.

The answer is C.
