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.

Ignore any minus sign. Example: I estimated 260 people, but 325 came. 260 â 325 = â65, ignore the â sign, so my error is 65. Percentage Error: show the error as a percent of the exact value ... so divide by the exact value and make it a percentage: 65/325 = 0.2 = 20%. Percentage Error is all about comparing a guess or estimate to an exact value. See percentage change, difference and error for other options.
