Is XY > X/Y
My Answer, which I cant understand to be wrong
A. XY>X/Y can be converted to Y^2>1. Statement 1 tells us that Y is a fraction and a fraction squared can never be greater than 1 (Y^2>1), so I concluded the answer "No", marking A as the correct answer. Can anybody explain what I did wrong?
XY>X/Y cannot be converted to Y^2>1. In an inequality, unless you know the sign -- in this case, of x, you cannot cancel the x on both sides.
In this case: if x>0
Y^2 > 1.
But if, x<0
then, Y^2 < 1.
