If x and y are positive integers such that x/y = 2.60, which of the following numbers could be y?	Answers:	A) 3	B) 4	C) 6	D) 5	E) 10
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 = 2.60 and because it's in the hundreds decimal place, put the given value (x/y = 2.60/1) and multiply it by 100.   Take the resulting fraction (x/y = 260/100) and reduce it to it's lowest form.   Both of the numbers are divisible by 20.   The result is x/y = 13/5.   Thus y = 5.   The correct answer is 5.
