Trying to figure out percentages

  1. Mar 6, 2013 #1
    Hi all,

    I'm a complete math idiot and was wondering if somebody could help me out with an equation that I'm trying to solve.

    Lets say I have the following percentages that equal 100%

    24.57%
    44.59%
    3.64%
    18.20%
    9%

    Now lets say I want to remove the 9% but I want the remaining 4 numbers to still equal 100%. How would I distribute the 9% difference? I should also add, I don't want to divide the 9% by 4 and then equal distribute that among the numbers I want them to absorb according to their current percentage. If that makes any sense at all.

    Thanks
    -Brandon

    First off, it's probably simpler to convert all of your numbers to decimal fractions, and get rid of the %. This makes your first four numbers
    .2457
    .4459
    .0364
    .1820

    Now divide each of these numbers by .91, which will give you a new set of numbers that will add to 1.0. All of the numbers will be proportionally larger than what you started with.
