Basic Percentage Calculation
To calculate what percentage X is of Y, divide X by Y and multiply by 100. For example, if you have 25 apples out of 100, 25 is 25% of 100.

To calculate percentage increase or decrease, find the difference between the new and original values, divide by the original value, and multiply by 100. A positive result indicates an increase, while a negative result indicates a decrease.
