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 225 and 36 is 189 (225 - 36 = 189).

Next, we need to find the average of the two numbers. The average of 225 and 36 is (225 + 36) / 2 = 130.5.

Now, we can calculate the percentage difference by dividing the absolute difference by the average and multiplying by 100. So, the percentage difference between 225 and 36 is (189 / 130.5) x 100 = 144.93%.

This means that the difference between 225 and 36 is 144.93% of the average of the two numbers. In other words, 225 is 144.93% greater than 36.
