If x and y are positive integers such that x/y = 4.25, which of the following numbers could be y?
Options:
A) 5	B) 4	C) 3	D) 17	E) 50
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 = 4.25 and because it's in the hundreds decimal place, put the given value (x/y = 4.25/1) and multiply it by 100.   Take the resulting fraction (x/y = 425/100) and reduce it to it's lowest form.   Both of the numbers are divisible by 25.   The result is x/y = 17/4.   Thus y = 4.   The correct answer is 4.
