1. Know what a percentage is. A percentage is a way to express a number as a part of a whole. To calculate a percentage, we look at the whole as equal to 100%. For example, say you have 10 apples (=100%).If you eat 2 apples, then you have eaten 2/10 Ã 100% = 20% of your apples and you are left with 80% of your original apples.. Know what a percentage is.

Calculate the average percentage by dividing the total items represented by percentages by the overall total of items. In the example, a total of 200 pencils were removed out of a total of 500 pencils. Divide 200 by 500, which is equal to 0.40.Convert to percentage form by multiplying 0.40 by 100.The average percentage removed equals 40 percent. percentage is a proportion (or ratio) that states the number of parts or items per 100. For example, if 37 percent of the pencils in a box of 100 pencils are red, this means 37 of the pencils are red. Percentages for more than one category can be averaged, but it can be a little tricky.
