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 130 and 93 is 37.

Next, we need to find the average of the two numbers. The average of 130 and 93 is (130+93)/2 = 111.5.

Now, we can find the percentage difference by dividing the absolute difference by the average and multiplying by 100. So, the percentage difference between 130 and 93 is (37/111.5) x 100 = 33.16%.

Therefore, the percentage difference between 130 and 93 is 33.16%. This means that 93 is 33.16% less than 130.
