Let us say you are required to find the increase or decrease in the value of a certain quantity over a while; instead of quoting the numbers, this comparison can be conveniently expressed as a percentage increase or a percentage decrease in quantity.Let's review what we've learned. A percentage increase or decrease is the amount of increase or decrease expressed as a percentage. To calculate it, we first calculate the first total and then the second total. If we are comparing two consecutive years, the first year gives us the first total, and the second year gives us the second total. Then we determine if there is an increase or decrease happening. Then we calculate the amount of this increase or decrease. To find the percentage, we divide the amount of increase or decrease by the first total and multiply by 100.
