Questions: (lb) to kilograms ( kg ), Round answer to the nearest tenth 103.4 21.4 21.32 102.5

Solution Steps

To convert pounds (lb) to kilograms (kg), we use the conversion factor where 1 pound is approximately 0.453592 kilograms. We will multiply each given weight in pounds by this conversion factor and round the result to the nearest tenth.

To convert from pounds (lb) to kilograms (kg), we use the conversion factor \(1 \, \text{lb} = 0.4536 \, \text{kg}\).

For each weight in pounds, multiply by the conversion factor to get the weight in kilograms. The calculations are as follows:

1. For \(103.4 \, \text{lb}\): \[ 103.4 \times 0.4536 = 46.91 \, \text{kg} \] Rounded to the nearest tenth: \(46.9 \, \text{kg}\).

2. For \(21.4 \, \text{lb}\): \[ 21.4 \times 0.4536 = 9.707 \, \text{kg} \] Rounded to the nearest tenth: \(9.7 \, \text{kg}\).

3. For \(21.32 \, \text{lb}\): \[ 21.32 \times 0.4536 = 9.667 \, \text{kg} \] Rounded to the nearest tenth: \(9.7 \, \text{kg}\).

4. For \(102.5 \, \text{lb}\): \[ 102.5 \times 0.4536 = 46.51 \, \text{kg} \] Rounded to the nearest tenth: \(46.5 \, \text{kg}\).
