To understand the percentage difference between 80 and 100, we first need to understand what percentage difference means. Percentage difference is a way to measure the difference between two values as a percentage of one of the values. In this case, we are comparing 80 and 100.
To calculate the percentage difference between 80 and 100, we need to first find the absolute difference between the two values. The absolute difference is simply the difference between the two values without considering whether one is greater than the other. In this case, the absolute difference between 80 and 100 is 20.
Next, we need to find the average of the two values. The average is simply the sum of the two values divided by two. In this case, the average of 80 and 100 is (80 + 100) / 2 = 90.
Finally, we can calculate the percentage difference by dividing the absolute difference by the average and multiplying by 100. In this case, the percentage difference between 80 and 100 is (20 / 90) x 100 = 22.22%.
So, the percentage difference between 80 and 100 is 22.22%. This means that 100 is 22.22% greater than 80.
