Question

Clare wants to mail a package that weighs 4 1/2 pounds. what could this weight be in kilograms

Answer 1

2 kg

Explanation:

we know that

`1\ lb=0.453592\ kg`

To convert pounds to kilograms, multiply by 0.453592

we have

`4(1)/(2)\ lb=4.5\ lb`

Convert to kg

`4.5\ lb=4.5(0.453592)=2.04\ kg`

Round to the nearest whole number

`2\ kg`
