How does the decimal point move when you rewrite a percent as a decimal and when you rewrite a decimal as a percent?

explain why the decimal point moves when you rewrite a percent as a decimal and when you rewrite a decimal as a percent.

Here is an example

0.40,what you do is if it is a decimal you move it to the right twice,until you get 40%,remove the 0 and you have a percent.To move a percent to a decimal,4% you go left twice such as 0.40,and then you are left with 40%

Sorry if it wasn't clear enough but that is my understanding of it.Have a great day.
