The percentage difference between 25 and 50 is calculated by finding the absolute difference between the two numbers, which is 25, and then dividing it by the average of the two numbers, which is 37.5. This gives us a result of 0.6667, which we can then multiply by 100 to get the percentage difference. Therefore, the percentage difference between 25 and 50 is 66.67%.

To understand this concept better, let's break it down further.

First, we need to find the absolute difference between the two numbers. Absolute difference means the difference between two numbers without considering their signs. In this case, the absolute difference between 25 and 50 is 25.

Next, we need to find the average of the two numbers. The average is calculated by adding the two numbers together and then dividing by 2. In this case, the average of 25 and 50 is 37.5.

Now, we can calculate the percentage difference by dividing the absolute difference by the average and then multiplying by 100. This gives us a percentage that represents how much one number differs from the other in relation to their average.

In summary, the percentage difference between 25 and 50 is 66.67%, which means that 50 is 66.67% greater than 25 in relation to their average.
