Final answer:
To convert 130 pounds to kilograms, divide the number of pounds (130) by the conversion factor (2.205), resulting in approximately 58.956 kg. Considering significant figures and rounding to the tenths place, the final answer is 59.0 kg.
Step-by-step explanation:
To convert 130 pounds to kilograms, we use the conversion factor 1 kilogram = 2.205 pounds. Since significant figures are important, we consider the precision of the conversion factor. The number 130 is exact and has an infinite number of significant figures, but the conversion factor has 4 significant figures due to the inexact number 2.205. Therefore, our calculated answer must be represented with an appropriate number of significant figures as well.
First, we convert pounds to kilograms using the formula:
-
- kilograms = pounds ÷ 2.205
Performing the calculation:
we find that 130 pounds is equivalent to approximately 58.956 kg. Considering significant figures and rounding to the tenths place, since the least precise measurement given in the question was to the tenth place, the final answer is 59.0 kg. This is because the least precise measurement dictates the precision of the final answer.
