x/y =2/3, then (x-y)/x? -1/2, -1/3, 1/3, 1/2, 5/2

Since this was in the last few probs of OG, thot that x/y could also be interpreted as x=-2 and y=-3 and therefore x/y can be equal to 2/3. OG proved me wrong, but is this a theoretical possibility?

we have this law of fraction:
a/b=c/d= (a-c)/(b-d)
