Convert 109 kilograms to pounds: Round your answer to the nearest tenth: pounds
The Correct Answer and Explanation is:
Correct Answer:
To convert 109 kilograms to pounds, use the conversion factor:
1 kilogram = 2.20462 pounds
Now multiply:109×2.20462=240.30358109 \times 2.20462 = 240.30358109×2.20462=240.30358
Rounded to the nearest tenth:240.3 pounds\boxed{240.3 \text{ pounds}}240.3 pounds
Explanation:
To convert a mass from kilograms to pounds, we use a conversion factor that relates the metric unit (kilogram) to the imperial unit (pound). The metric system is used worldwide and is based on units of ten. In contrast, the imperial system is commonly used in the United States for measuring weight, length, and volume.
The standard conversion factor is:1 kilogram=2.20462 pounds1 \text{ kilogram} = 2.20462 \text{ pounds}1 kilogram=2.20462 pounds
This means that every kilogram is equivalent to approximately 2.2 pounds. When converting kilograms to pounds, multiply the number of kilograms by this factor.
In this case, you are given 109 kilograms. Multiply this by the conversion factor:109×2.20462=240.30358109 \times 2.20462 = 240.30358109×2.20462=240.30358
Since the question asks for the result to be rounded to the nearest tenth, we look at the digit in the hundredths place. The digit after the decimal point is 3, and the next digit is 0. Because 0 is less than 5, we round down and leave the 3 unchanged. This gives:240.3 pounds240.3 \text{ pounds}240.3 pounds
This conversion is especially useful in science, travel, fitness, and cooking when working with systems that use different units. Accurate conversions ensure consistency, particularly when precision is important. Always remember to check how many decimal places or what level of rounding is required in a problem. In this case, the nearest tenth means keeping one digit after the decimal point.
