Answer 1

Explanation:

In order to complete the table, we need to know the equivalences between the units.

We know that 1,000 meters is equal to one kilometer and that 100,000 centimeters is equal to one kilometer.

Therefore:

`\begin{gathered} 421\text{ km}\cdot\frac{1000\text{ m}}{1\text{ km}}=421000\text{ m} \\ \\ 421\text{ km}\cdot\frac{1000\text{ cm}}{1\text{ km}}=42100000\text{ cm} \end{gathered}`
