If the positive integer x is a multiple of 5/2 and the positive integer y is a multiple of 2, then xy must be a multiple of which of the following?
I. 1
II. 12
III. 5
Choose the correct choice from the following answers.
A) II only
B) I and II only
C) I and III only
D) II and III only
E) I, II, and III
x=5/2a   y=2b   xy=5ab   where a,b are integers   Hence , xy will always be divisible by 1,5 .   I and III only is the answer.
