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 480 and 72 is 408 (480 - 72 = 408).

Next, we need to find the average of the two numbers. The average of 480 and 72 is (480 + 72) / 2 = 276.

Now, we can calculate the percentage difference by dividing the absolute difference by the average and multiplying by 100. So, the percentage difference between 480 and 72 is (408 / 276) x 100 = 147.83%.

This means that the second number (72) is 147.83% less than the first number (480). Alternatively, we can say that the first number is 247.83% greater than the second number.
