Solution
Solution Steps
To convert Bella's weight from pounds to kilograms, we use the conversion factor: 1 pound is approximately 0.453592 kilograms. Multiply Bella's weight in pounds by this conversion factor to get her weight in kilograms.
Step 1: Conversion Factor
To convert from pounds to kilograms, we use the conversion factor:
\[
1 \text{ lb} \approx 0.453592 \text{ kg}
\]
Step 2: Calculation
We calculate Bella's weight in kilograms using the formula:
\[
\text{Weight in kg} = \text{Weight in lb} \times \text{Conversion Factor}
\]
Substituting the values:
\[
\text{Weight in kg} = 55 \text{ lb} \times 0.453592 \text{ kg/lb} \approx 24.9476 \text{ kg}
\]
Step 3: Rounding
Rounding the result to four significant digits, we have:
\[
\text{Weight in kg} \approx 24.95 \text{ kg}
\]
