C) 7 over 4 and 5 over 9
D) 3 over 8 and 2 over 3

Answer 1

The easiest way to make a fraction into a decimal is to divide the numerator by the deniminator. Since terminating is a decimal that ends, and doesn't repeat, the answer would have to be A. To eliminate, 5/9 is 0.555.. so it's not the answer.7/4 is 1.75, but 5/9 is 0.55... 3/8 is 0.375, but 2/3 is 0.666
