Final answer:

The answer, when rounded to the tenths place, is approximately 63.0 kg.

Explanation:

To convert 139 pounds (lbs) to kilograms (kg), we need to use the conversion factor where 1 kilogram equals approximately 2.205 pounds. Here's a step-by-step breakdown to perform the conversion:

  • First, write down the weight in pounds that you want to convert (139 lbs).
  • Next, use the conversion factor 1 kg = 2.205 lbs.
  • To find the weight in kilograms, divide the number of pounds by 2.205:

139 lbs ÷ 2.205 lbs/kg = 63.038kg (unrounded)

Finally, consider the precision of the measurements. If the least precise measurement given is to the tenths place, such as 13.7 kg, then we would round our final answer to the tenths place as well. In this case, when rounded to the tenths place, 139 lbs is approximately 63.0 kg.
