If x and y are positive integers such that x/y = 6.8, which of the following numbers could be y?	Pick one:
A) 1	B) 3	C) 2	D) 6	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 = 6.8 and because it's in the tens decimal place, put the given value (x/y = 6.8/1) and multiply it by 10.   Take the resulting fraction (x/y = 68/10) and reduce it to it's lowest form.   Both of the numbers are divisible by 2.   The result is x/y = 34/5.   Thus y = 5.   The correct answer is 2.
