175 kg
Solution
Solution Steps
Step 1: Understand the Conversion Factor
The problem provides a conversion factor: \(1 \, \text{kg} = 2.205 \, \text{lb}\). This means that to convert pounds to kilograms, we need to divide the weight in pounds by 2.205.
Step 2: Apply the Conversion
To find out how many kilograms an individual weighing 175 pounds would be, we use the conversion factor:
\[
\text{Weight in kg} = \frac{\text{Weight in lb}}{2.205}
\]
Substituting the given weight:
\[
\text{Weight in kg} = \frac{175}{2.205} \approx 79.3651
\]
Step 3: Round to Four Significant Digits
The result from the calculation is approximately 79.3651 kg. Rounding this to four significant digits gives us 79.37 kg.
Final Answer
The weight of a 175 lb individual in kilograms is \(\boxed{79.37 \, \text{kg}}\).
