Question

Convert 86000 cm to km. Show all of your work. Last one!

Answer 1

Well, usually what I do, when converting simple forms like these, that are in the same set. (meters)
Compare CM to Meters
1 CM = 0.01 M
Compare KM to M
1 KM = 1000 M
So we notice that they are 5 decimals off
Since, we are converting to Kilometers, we will go 5 decimals back, so
instead of 86000
we go |
making it, 0.86
pretty simple ;3

Answer 2

100cm=1m and 1000m=1km
thus 100000cm=1km
if 100000cm=1km then what would 86000cm be?
just divide 86000 by 100000
this gives you the answer in metres
