When an amount of anything changes over time we often want to understand how big the change was. This happens very often in the financial world to help us gauge our trajectory. Is our business failing or succeeding? Percentage of change tells us this. There are two methods for determining percentage of change. Method 1 is to subtract the old value from the new value and then divide that by the old value. To convert it to a percentage just multiply it by one hundred. Method 2 is to divide the new value by the old value and multiply it by one hundred. You would finish that off by subtracting one hundred percent.
Your students will use these worksheets to learn how to calculate the percent change between two values. Changes may be positive (addition) or negative (subtraction). All necessary formulas have been included.
