Explanation:

Identify the conversion factor

Using the Unit Conversion, U.S. Customary System, and Metric System knowledge points

$$ 1\text{ kg} = 2.2\text{ lb} $$

Set up the conversion equation

Using the Unit Conversion knowledge point

$$ \text{Weight in kg} = \frac{25\text{ lb}}{2.2\text{ lb/kg}} $$

Calculate the weight in kilograms

Using the Unit Conversion knowledge point

$$ \text{Weight} = 11.3636\dots\text{ kg} $$

Round to the nearest hundredth

Using the Unit Conversion knowledge point

$$ 11.3636\dots \approx 11.36\text{ kg} $$
