how do you convert centimeter into meteres

Answer 1

100 cm = 1 meter

Divide the centimeters by 100 to find the number of meters.

Answer 2

to convert units, always multiply by something/the same thing in other units.

For example there are ten gophs in one bork

10 gophs/ 1 bork is the same top and bottom so if I multiply by that or its inverse I change nothing.

so
if I have 15 borks
and want to express that in gophs
I do:

15 borks ( 10 gophs/1bork) = 150 gophs

or

if I have 30 gophs and want to express that in borks I do:

30 gophs ( 1 bork /10 gophs) = 3 borks

If you multiply by something that is the same top and bottom, you do not change it, only its words :) It is basically one.
