To find the weight in pounds for an item that weighs 45 kilograms using the conversion formula (which is generally \( \text{pounds} = \text{kilograms} \times 2.2 \)), we can calculate:
\[ \text{pounds} = 45 \text{ kg} \times 2.2 \approx 99 \text{ pounds} \]
So, if an item weighs 45 kilograms, its weight in pounds is approximately 99.
The correct answer is 99.
