Answer :
Final answer:
To convert 165 pounds to kilograms using the formula 1 kg = 2.205 lb, divide 165 by 2.205 to get 74.8304 kg. When rounded to three significant figures, the answer is 74.8 kg.
Explanation:
To convert 165 pounds to kilograms using the formula that 1 kilogram is equivalent to 2.205 pounds, you would perform the following calculation:
- First, write down the conversion relation: 1 kg = 2.205 lb.
- Next, divide the weight in pounds you want to convert (165 lb) by the number of pounds in one kilogram (2.205 lb).
- Perform the division: 165 lb ÷ 2.205 lb/kg = 74.8304 kg.
- Now determine the appropriate number of significant figures (SF) to use in the answer. The given value, 165 pounds, is an inexact number but is presented with three SFs. However, because 2.205 has four SFs, it does not limit the precision of our answer. Hence, our answer should be presented with three SFs.
- Thus, rounded appropriately to three SFs, the conversion of 165 pounds is 74.8 kg.
Answer: Around 74.83 kg
Step-by-step explanation: You need to divide 2.205 into 165.
