To find the percentage difference between two numbers, we first need to find the absolute difference between them. In this case, the absolute difference between 72 and 62 is 10.

Next, we need to find what percentage of the original number the absolute difference represents. To do this, we divide the absolute difference by the original number (in this case, 72) and then multiply by 100 to get the percentage.

So, the percentage difference between 72 and 62 is:

(10/72) x 100 = 13.89%

This means that 13.89% of 72 is equal to the absolute difference between 72 and 62. In other words, 10 is 13.89% of 72.
