0.001 (option A)
Explanation:The mass of a paper clip is about 1g. We are to find the value of 1g in kg
[tex]1000g\text{ = 1 kilogram}[/tex]We convert from gram to kg
let the value of 1g in kg = x
1000g = 1kg
1g = x
cross multiply:
x(1000) = 1(1)
1000x = 1
divide both sides by 1000:
[tex]\begin{gathered} \frac{1000x}{1000}\text{ = }\frac{1}{1000} \\ x\text{ = }\frac{1}{1000}\text{ kg} \end{gathered}[/tex]The options are in decimals we need to 1/1000 to decimal:
[tex]\begin{gathered} In1000,\text{ there are 3 zeros after 1. We would move backwards 3 times starting from 1} \\ \frac{1}{1000}\text{ = 0.001} \end{gathered}[/tex][tex]1g\text{ = 0.001 kg (option A)}[/tex]
