In this post, I want to share two percent of a number cheat sheets for a consumer math unit on calculating percentages of numbers and calculating discounts. Each can be added to student notebooks as a reference when learning how to calculate percentages.

| Percent of a number cheat sheet |
The first percent sheet reminds students of the divisor when calculating the percent of a number. For example, We can divide 125 by 5 to find that 25 is 20% of 125. This sheet prints on half a page to fit into a student notebook.

| Friendly percentages cheat sheet |
The second is a friendly percentages reference that's helpful for calculating discounts. If a shirt is 15% off, we can calculate the shirt's price by finding 85% of the original cost of the shirt. I always find this easier than calculating 15% then subtracting that amount from the original price.
This friendly percentages sheet can also be referenced during an exponentials unit when calculating decay. If the value of a car is depreciating by 15% per year, we can use .85 as the exponential's base.
The two sheets are found free in the same download here: Free percent of a number cheat sheets
