问题 If x and y are odd integers, which of the following must always be a non-integer?

选项 A、xy
B、x/y
C、y/x
D、xy/2
E、-xy

答案 D

解析 Since we know that x and y are odd, xy must always be odd. Therefore, xy/2 will always be a non-integer. None of the other answer choices has this relationship; in all of the other cases, it is possible to have values of x and y that would yield integer results.
