Answer the question on the basis of the information given below.
\[ P \# Q = \frac{P+PQ}{Q} \] \[ P \, \$ \, Q = \frac{P-PQ}{Q} \] \[ P \; ? \; Q = \frac{Q+PQ}{P} \] \[ P \, @ \, Q = \frac{Q-PQ}{P} \]
The value of \( \left( \dfrac{P \# Q}{P \, \$ \, Q} \right) \div \left( \dfrac{P \; ? \; Q}{P \, @ \, Q} \right) \), where \(P = 1\) and \(Q = 2\), is
