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 294 and 6 is 288 (294 - 6 = 288).

Next, we need to find the average of the two numbers. The average of 294 and 6 is (294 + 6) / 2 = 150.

Now, we can calculate the percentage difference by dividing the absolute difference by the average and multiplying by 100. So, the percentage difference between 294 and 6 is (288 / 150) x 100 = 192%.

This means that the second number (6) is 192% less than the first number (294). Alternatively, we can say that the first number is 192% greater than the second number.
