B.
125 \mathrm{lb} \times \frac{28 \mathrm{~g}}{1 \mathrm{oz}}
C.
125 \mathrm{lb} \times \frac{1 \mathrm{lb}}{28 \mathrm{~g}} \times \frac{1 \mathrm{~kg}}{1000 \mathrm{~g}}

Step 2:: Identify the conversion factors
To convert pounds (lb) to kilograms (kg), we need to: - Convert pounds to ounces - Convert ounces to grams - Convert grams to kilograms
Step 3:: List the conversion factors
- 1 lb = 16 oz - 1 oz = 28 g - 1 kg = 1000 g
Step 4:: Set up the conversion calculation
125 \mathrm{lb} \times \frac{16 \mathrm{oz}}{1 \mathrm{lb}} \times \frac{28 \mathrm{~g}}{1 \mathrm{oz}} \times \frac{1 \mathrm{~kg}}{1000 \mathrm{~g}}
Step 5:: Calculate
125 \times 16 \times 28 \times \frac{1}{1000} = 56.7 \mathrm{~kg}
Final Answer
The correct solution is option A, which shows the complete and correct conversion process.
