How do you express 1.65×10^4km as a multiple of 6.38x10^6 m?

Answer 1

1.65*10^7 m/6.38*10^6 m = 2.586

The first quantity is 2.586 times the second quantity.

Note that I had to convert both to the same dimensions before dividing. I chose meters. The ratio would be the same if chose cm or km.

Answer 2

Oh I see. Thank you!
