Tony bought a melon that weighs 48 ounces. He wants to know its weight in pounds.

To convert the weight of the melon from ounces to pounds, you can use the conversion factor that 1 pound is equal to 16 ounces.

To find the weight in pounds, you can divide the weight in ounces by the number of ounces in a pound:

\[ \text{Weight in pounds} = \frac{\text{Weight in ounces}}{16} \]

Now, plug in the weight of the melon:

\[ \text{Weight in pounds} = \frac{48 \text{ ounces}}{16} = 3 \text{ pounds} \]

So, the melon weighs 3 pounds.
