Find the absolute difference between two numbers: |20 - 30| = |-10| = 10. Find the average of those two numbers: (20 + 30) / 2 = 50 / 2 = 25. Divide the difference by the average: 10 / 25 = 0.4. Express it as percentages: 0.4 * 100 = 40%

How to Find the Difference between Two Numbers. To find the difference between two numbers, subtract the number with the smallest value from the number with the largest value. The product of this sum is the difference between the two numbers. Therefore the difference between 45 and 100 is 55.

First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100.

Subtract the mean from the data for which you want a standard score. In the example, 28 minus 24 equals 4. Divide the difference between the data and the mean by the standard deviation. In the example, 4 divided by 5 equals a standard score of 0.8.
