I am drawing a blank. I am developing a comprehensive budget and am required
to show the percentage for each of the expenditures. In the end, the
percentages should total to 100.

Example,

$66.00 out of $100.00 = 20%

$44.00 out of $100.00 = 10%

$33.00 out of $100.00 = 90%

I do not remember how to put formulate the formula in excel 2007.

Please help.
