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 97 and 83 is 14.

Next, we need to find the average of the two numbers. The average of 97 and 83 is (97+83)/2 = 90.

Now, we can find the percentage difference by dividing the absolute difference by the average and multiplying by 100. So, the percentage difference between 97 and 83 is (14/90) x 100 = 15.56%.

Therefore, the percentage difference between 97 and 83 is 15.56%. This means that 97 is 15.56% greater than 83.
