Answer 1

To convert pounds to kilograms using the proportion \(1 \text{ kilogram} = 2.2 \text{ pounds}\), we can rearrange the proportion to find out how many kilograms are equal to 72 pounds:

\[
\text{kilograms} = \frac{\text{pounds}}{2.2}
\]

Now substituting 72 pounds into the formula:

\[
\text{kilograms} = \frac{72}{2.2} \approx 32.7273
\]

Rounding to the nearest tenth gives us:

\[
32.7 \text{ kilograms}
\]

Thus, the correct answer is:

**32.7**
