Final answer:
To convert Clare's package weight from pounds to kilograms, multiply 4 ½ pounds (4.5 pounds) by the conversion factor 0.45 kg/lb to get approximately 2.025 kilograms.
Step-by-step explanation:
Clare wants to mail a package that weighs 4 ½ pounds. To convert this weight to kilograms, which is a metric unit of mass, we can use the conversion factor that 1 pound is approximately equal to 0.45 kilograms. Using this knowledge, we can calculate:
4 ½ pounds = 4.5 pounds
The conversion formula is:
Weight (kg) = Weight (lb) × 0.45 kg/lb
So for Clare's package:
Weight (kg) = 4.5 lb × 0.45 kg/lb
Weight (kg) = 2.025 kg
Therefore, Clare's package weighs approximately 2.025 kilograms.
It's important to note that when converting, it's valuable to remember the appropriate metric unit to use for a given situation, similar to how Jesse determined which metric unit was suitable for weighing the box mentioned earlier.
