Explanation:

Step1: Recall conversion factor

We know that 1 pound = 16 ounces. So the conversion factor is $\frac{1\ lb}{16\ oz}$.

Step2: Perform unit - conversion

If we have $n$ ounces and we want to convert it to pounds, we multiply $n$ ounces by the conversion factor $\frac{1\ lb}{16\ oz}$. So $n\ oz=\frac{n\ oz}{1}\cdot\frac{1\ lb}{16\ oz}=\frac{n}{16}\ lb$.

Answer:

$\frac{n}{16}$
