If s and t are positive integers such that s/t = 56.12, which of the following could be the remainder when s is divided by t ?	Choose the correct option.
A) 2	B) 4	C) 8	D) 20	E) 90
The remainder is 0.12 or 12/100. You can go one step further and say that X/Y=12/100, where X and Y are whole numbers. Plug in all the answer choices for X and see which one makes Y a whole number.   One thing that jumps out at me is that A, B, C, and D are all even. E on the other hand is odd. Why? Maybe I'll start plugging in here first.   90/Y=12/100   12Y=9000   Y=750   Answer: 90.
