Answer 1

To convert pounds to kilograms using the proportion \( 1 \text{ kilogram} = 2.2 \text{ pounds} \), you'll want to set up the conversion as follows:

1. Start with the given weight in pounds: \( 72 \text{ pounds} \).

2. Use the conversion factor to find how many kilograms that is:

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

   Plugging in the values:

   \[ \text{kilograms} = \frac{72}{2.2} \approx 32.7272727272 \]

3. Round this to the nearest tenth:

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

Therefore, \( 72 \text{ pounds} \) is approximately \( 32.7 \text{ kilograms} \).

The correct response is 32.7.
