GRE quantitative question

Why / how are these quantities not equal?

Question: which Quantity is greater; answer -- Quantity B is greater.

A: n*m / m-n

B: p

The following equation is provided: 1/n - 1/m = 1/p

I isolated p such that p = m*n / (m-n). Therefore, the two quantities should be equal?!
