To find an average, 1. you add up all the numbers to find a sum. Example: Molly made these grades on her tests: 92,87,89,91, and 96. What is the average of her grades? 92+87+89+91+96= 455. 2. you count up the amount of whole numbers (5), and then divide that by 455. 3. 455 divided by 5= 95. The average is 95.
20+23 = 43 and 43/2 = 21.5 which is the mean average
