(a) To convert the weight of an object from kilograms (kg) to pounds (lb), you use the facts that a weight measured in kilograms is proportional to a weight measured in pounds and that 1 kg corresponds to $2.20 \mathrm{lb}$. Find an equation that relates weight measured in kilograms to weight measured in pounds. (b) Use your answer in (a) to convert the following measurements: (i) $63 \mathrm{lb}$ (ii) $5 \mathrm{lb}$ (iii) $2.5 \mathrm{~kg}$ (iv) $76 \mathrm{~kg}$

Step 1
20 lb. Let's denote the weight in kilograms as $w_{kg}$ and the weight in pounds as $w_{lb}$. We can write the proportionality equation as: $$w_{kg} = k \cdot w_{lb}$$ where $k$ is the proportionality constant. We know that when $w_{kg} = 1$, $w_{lb} = 2.20$. So, Show more…
