add all the #s up, then divide by the number of numbers. It's the average. You add all the numbers together and however many numbers there are you divide by that number. For example: 12, 11, 7, and 10 Add them and they equal 40. There are four numbers so you divide 40 by 4 and get 10. That's the mean
You add the numbers. Then you divide by the number of numbers (i.e., if you have three numbers, you divide the sum by 3).You add the numbers. Then you divide by the number of numbers (i.e., if you have three numbers, you divide the sum by 3).You add the numbers. Then you divide by the number of numbers (i.e., if you have three numbers, you divide the sum by 3).You add the numbers. Then you divide by the number of numbers (i.e., if you have three numbers, you divide the sum by 3).
To find the average you need to add the two numbers together and divide by two. 18 + 22 = 40 40 / 2 = 20 The answer is 20.
5/6. You take the greatest common factor and divide both numbers by it.
Let the two numbers be x and y. Let suppose that the average of two numbers is 20. Then,x + y = 40 and 40/GCF = 5, where GCF = 40/5 = 8Since LCM is 48 and GCF is 8, the numbers are 16 and 24, whose average is 20 is true.
