Best ResponseYou've already chosen the best response.0because usually its x/y right? so the inverse would be y/x

Best ResponseYou've already chosen the best response.1You are correct that "usually" you see expressions like x/y in class and the inverse of x/y is y/x, but that is not what this question is asking for.
