Well kiddo, percent difference tells us how much one thing is different from another thing in percentage form. Let's say you have two apples, and one apple is bigger than the other. We can use percent difference to figure out how much bigger the bigger apple is compared to the smaller one.
First, we need to figure out the difference between the sizes of the apples. To do that, we can subtract the smaller apple from the bigger apple. Let's say the bigger apple is 10 centimeters and the smaller apple is 8 centimeters. If we subtract 8 from 10, we get 2.
Now we know that the bigger apple is 2 centimeters bigger than the smaller apple. To find out the percent difference, we need to divide the difference by the smaller apple's size and multiply by 100. So, we do 2 divided by 8, and get 0.25. If we multiply 0.25 by 100, we get 25.
Therefore, the bigger apple is 25% bigger than the smaller apple. We can use percent difference to compare lots of things, like prices or test scores, and see how much one thing is different from another thing.
