Answer 1

An item that weighs 45 kilograms is approximately 99 pounds when converted using the standard conversion factor of 1 kg = 2.205 pounds.

Step-by-step explanation:

To convert weight from kilograms to pounds, you use a conversion factor that states 1 kilogram is approximately equal to 2.205 pounds.

To find the weight in pounds of an item that weighs 45 kilograms, you multiply the weight in kilograms by this conversion factor.

Here is the calculation step-by-step:

1. Start with the known weight in kilograms: 45 kg.
2. Use the conversion factor 1 kg = 2.205 lbs.
3. Multiply the two: 45 kg * 2.205 lbs/kg = 99.225 lbs.
4. Since we are looking for an approximate weight in pounds, we can round to the nearest whole number if necessary, which gives us 99 lbs.

Therefore, an item that weighs 45 kilograms is approximately 99 pounds.
