A terminating decimal is defined as a decimal that has a finite number of nonzero digits. Examples of terminating decimals are 0.24, 52, and 6.0314. x and y are positive integers. If x/y is expressed as a decimal, is it a terminating decimal?
(1) 50 < x < 60
(2) y = 9
The OA is E.

Let's go straight to....
Statements 1 and 2 combined
There are several values of x and y that satisfy BOTH statements. Here are two:
Case a: x = 54 and y = 9. So, x/y = 6. In this case, the decimal equivalent of x/y IS a terminating decimal
Case b: x = 55 and y = 9. So, x/y = 6.33333333........ In this case, the decimal equivalent of x/y is NOT a terminating decimal
Since we cannot answer the target question with certainty, the combined statements are NOT SUFFICIENT
Answer: E
