Calculating Percent Change and Division

This video tutorial explains how to calculate the percent of change between two numbers using three simple steps: subtracting the original number from the new number, dividing the result by the original number, and converting the decimal to a percent. The tutorial provides examples of both percent increase and decrease, and offers guidance on using a calculator for these calculations. It also covers how to round the final result to the nearest tenth or whole percent, depending on the requirement.
