question 16
100 lbs = ___ kg

Explanation:

Step1: Recall the conversion factor

We know that \( 1\space lb\approx0.453592\space kg \).

Step2: Calculate for 100 lbs

To find the equivalent in kilograms for 100 lbs, we multiply 100 by the conversion factor: \( 100\times0.453592 = 45.3592 \). So, \( 100\space lbs\approx45.36\space kg \) (rounded to two decimal places) or approximately 45.4 kg (rounded to one decimal place), and a common approximate value used sometimes is 45 kg (for simplicity in some contexts) or more accurately around 45.36 kg.

Answer:

Approximately \( 45.36 \) (or \( 45.4 \) or \( 45 \) depending on the required precision; the exact conversion gives \( 100\times0.453592 = 45.3592 \))
