Question

1. his rucksack has a total mass of 25 pounds. translate this amount to kilograms rounding to the nearest kilogram.

Explanation:

Step1: Recall the conversion factor

We know that 1 pound is approximately equal to 0.453592 kilograms. So the conversion formula from pounds to kilograms is \( \text{Mass in kg} = \text{Mass in pounds} \times 0.453592 \).

Step2: Substitute the given value

The mass of the rucksack is 25 pounds. Substituting into the formula, we get \( \text{Mass in kg} = 25 \times 0.453592 \).

Step3: Calculate the result

First, calculate \( 25\times0.453592 = 11.3398 \) kilograms.

Step4: Round to the nearest kilogram

Rounding 11.3398 to the nearest whole number, we look at the decimal part. The decimal part is 0.3398, which is less than 0.5, so we round down. So the result is 11 kilograms.
