If x and y are odd integers, which of the following must always be a non-integer? Choose the correct choice from the following:
A) xy
B) x/y
C) y/x
D) xy/2
E) -xy
A) xy: (1)(1) = 1 and 1 is an integer. ELIMINATE   B. x/y: 1/1=

1 and 1 is an integer. ELIMINATE   D. xy/2   E. -xy: -(1)(1)= -1 and -1 is an integer. ELIMINATE   As X and Y are odd, multiplication of x and y would result in odd integer   (Odd Integer)/2 will always be non integer   ANSWER:xy/2
<result>D</result>
