Answer 1

To convert pounds to kilograms using the proportion \(1 \text{ kilogram} = 2.2 \text{ pounds}\), you can set up the following equation:

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

Substituting 72 pounds into the equation:

\[ \text{kilograms} = \frac{72}{2.2} \approx 32.72727272727273 \]

Rounding to the nearest tenth gives you:

\[ \approx 32.7 \text{ kilograms} \]

So, the correct response is 32.7.
