To determine how many kilograms a 150-pound patient weighs, we need to convert pounds to kilograms using the given conversion factor, 1 kilogram equals 2.2 pounds.
Step-by-step solution:
1. Identify the given values:
- The weight of the patient: 150 pounds.
- Conversion factor: 1 kilogram = 2.2 pounds.
2. Set up the relationship for conversion:
- We need to find the weight in kilograms (weight_kg). To do this, we can use the relationship:
\(\[
\text{weight\_kg} = \frac{\text{weight in pounds}}{\text{pounds per kilogram}}
\]\)
3. Substitute the known values into the relationship:
- The weight in pounds is 150.
- The conversion factor (pounds per kilogram) is 2.2.
\(\[
\text{weight\_kg} = \frac{150}{2.2}
\]\)
4. Perform the division:
- Dividing 150 by 2.2 gives approximately 68.18181818181817 kilograms.
So, a 150-pound patient weighs approximately 68.18 kilograms.
