If x and y are positive integers such that x/y = 0.875, which of the following numbers could be y?  Select:	A) 3	B) 2	C) 4	D) 10	E) 8
With the given information, we are trying to find the value of y.   To achieve this we must convert the given decimal to a fraction and reduce it to it's lowest integer form.   Take the decimal x/y = 0.875 and because it's in the thousands decimal place, put the given value (x/y = 0.875/1) and multiply it by 1,000.   Take the resulting fraction (x/y = 875/1000) and reduce it to it's lowest form.   Both of the numbers are divisible by 125.   The result is x/y = 7/8.   Thus y = 8.   The correct answer is 8.
