Question

Each American throws out an average of 1650lb of garbage per year. Convert this weight to kilograms using the fact that 1kg=2.2lb.

Answer 1

Given that

`\begin{gathered} 1\text{ kg = 2.2lb} \\ \\ \Rightarrow1\text{ lb = }(1)/(2.2)\text{ kg} \\ \\ \text{ multiplying both sides by }1650\text{ } \\ \\ \Rightarrow1650*1\text{ lb}=1650*(1)/(2.2)\text{ kg} \\ \\ \Rightarrow1650\text{ lb }=(1650)/(2.2)\text{ kg} \\ \\ \Rightarrow1650\text{ lb}=750\text{ kg} \end{gathered}`

Therefore, 1650 lb is 750 kg.
