To find the percentage difference between 3 and 250, we first need to calculate the absolute difference between the two numbers. Absolute difference means the difference between two numbers without considering their signs.

So, the absolute difference between 3 and 250 is:

|250 - 3| = 247

Now, to find the percentage difference, we need to divide the absolute difference by the average of the two numbers and then multiply by 100.

The average of 3 and 250 is:

(3 + 250) / 2 = 126.5

So, the percentage difference between 3 and 250 is:

(247 / 126.5) x 100 = 195.05%

Therefore, the percentage difference between 3 and 250 is 195.05%. This means that 250 is 195.05% more than 3.
