Hi there!

I'm wondering what function I should be using to transform numbers I already have into percentages (I have been strictly told that it is possible to do this USING ONE SINGLE FUNCTION).

Here's my initial data: http://puu.sh/mWAdt/9655d0a1e6.png

Here's what it should look like in percentages: http://puu.sh/mWAhT/eec32beb0f.png

I'm not asking how to change my values in percentages once I have them, I'm asking how to actually transform them in percentages by using one single function. I could easily do them individually by dividing my initial data by the total amount but I've been told there's a way to do it all in with one function. I'm sure it has to do with using absolute reference ($X$X), but if I try to put a column, my initial value disappears and therefore I can't make the calculation.

Any help would be greatly appreciated. =)
