Can someone do this for me? ? i don’t understand all of it

I’m pretty sure the answers are:

250 meters=0.25 kilometers

12 meters=0.012 kilometers

1 meter=0.001

5 kilometers=5,000 meters

20 kilometers=20,000 meters

0.3 kilometers=300 meters

For future reference, you can find the constant of proportionality by dividing the x value by the y value. Then you multiply each given number by the constant of proportionality, and that’ll give you your answers.

Unfortunately, I don’t know the answers to the last few questions. Sorry about that!
