Let’s look at our facts.
- There are 100cm in a meter.
— To convert cm into m, we divide by 100.
— To convert m into cm, we multiply by 100.
This means to convert 8.6m into cm, we multiply 8.6 by 100.
An easy way to do this is moving the decimal point two places to the right.
This leaves us with 860cm.
Hope this helps! :)
