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 36 and 60 is 24 (60 - 36 = 24).

Next, we need to find the average of the two numbers. The average of 36 and 60 is (36 + 60) / 2 = 48.

Now, we can find the percentage difference by dividing the absolute difference by the average and multiplying by 100. So, the percentage difference between 36 and 60 is (24 / 48) x 100 = 50%.

This means that 60 is 50% more than 36, or that 36 is 33.33% less than 60. It's important to note that the percentage difference is always relative to the average of the two numbers, and can be positive or negative depending on which number is larger.
