To find the percentage difference between two numbers, we first need to calculate the absolute difference between them. In this case, the absolute difference between 88 and 112 is 24 (112 - 88 = 24).

Next, we need to find the average of the two numbers. The average of 88 and 112 is (88 + 112) / 2 = 100.

Now, we can calculate the percentage difference by dividing the absolute difference by the average and multiplying by 100. So, the percentage difference between 88 and 112 is (24 / 100) x 100 = 24%.

Therefore, the percentage difference between 88 and 112 is 24%. This means that 112 is 24% more than 88, or that 88 is 24% less than 112.
