Question

A bag of rice weighs 3.18 pounds. Find its mass in kilograms. ( 1 kilograms = 2.2 feet )

Answer 1

there are 2.2lbs in 1kg, so, how many kg in 3.18lbs?


`\bf \begin{array}{ccll} lbs&kg\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 2.2&1\\ 3.18&k \end{array}\implies \cfrac{2.2}{3.18}=\cfrac{1}{k}\implies k=\cfrac{3.18\cdot 1}{2.2}`
