The percentage error gives you the difference between the approximate and exact values as a percentage of the exact value and can help you see how close your guess or estimate Absolute Error and Relative Error: Error in measurement may be represented by the actual amount of error, or by a ratio comparing the error to the size of the measurement. Simply divide -1, the result when 10 is subtracted from 9, by 10, the real 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.
