Answer 1

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

$$\text{kilograms}=\frac{\text{pounds}}{2.2}$$

Now, substituting $72$ pounds into the equation:

$$\text{kilograms}=\frac{72}{2.2}\approx 32.727$$

Rounding to the nearest tenth of a kilogram, we get:

$$\text{kilograms}\approx 32.7$$

So, the answer is 32.7 kilograms.
