Answer: I agree with Moriah. If two equations represent the same proportional relationship, then they should have the same constant of proportionality. In this case, the constant of proportionality in p = 1.5 and 2/3p = q is different, so the two equations cannot represent the same proportional relationship.
It's possible that the two equations represent two different proportional relationships, but without more information it's impossible to determine if that is the case.
