OOps sorry, stem 1 should read 'the GCF of x/2 and y/2 is 5'.

i also have A but i think GCF for the situation in A would be 10 rather than 5.

ex. 10/2 and 30/2

anything ending in 5 would not be an integer when divided by 2.

The answer is A.

Ice T I am no sure what you mean by "anything ending in 5 would not be an integer when divided by 2."

Its given that the number does not end in 5 becuase X/2 and Y/2 are integers. Therefore X & Y has to be even integers.
