Percentage of a column of numbers

[David Hill]

I have several columns of numbers. Here is one for example:

0
3
1
2
3
4
9
8
12

I need to find out what % of 45 each of these is. (I know they do not add up to 45) I have a bunch of these to do. All help is appreciated.

If the first is in A1, =A1/45, then format as a % and drag down.
