Question

Can someone please help me

Answer 1

5km=5000m

Because the rate to this is: 1:1000

Answer 2

Explanation:

`\text{5 km}*(1000 m)/(1 km) = 5000m`

Notice that the units cancel out. You always want that to happen. Depending on your grade level and your teacher, you can avoid the proportion by doing the question this way. Always make sure you arrange it so that 1 set of units will cancel.
