5 & 17
5 + 8 + 2 = 15. 15 / 3 = 5 All you have to do is add the numbers, then divide the answer by how many numbers you added.
The mean is very simple. It is the average. You count the numbers all together then divide by how many numbers there are. Example: there are 5 numbers. 1, 2, 3, 4 and 5 add them all together 1 + 2 + 3 + 4 + 5 = 15 then since there are 5 numbers, divide 15 by 5 15 divided by 5 = 3
Add the five numbers together and then divide that number by 5
1, 2, 4, 5, 10, and 20 divide evenly into 20.
prime numbers that divide into 1155 = 3, 5, 7, 11
The idea is to add the five numbers, then divide the result by 5 (in this case, you divide by 5, because there are 5 numbers).
1, 5, 25.

5 & 17
You can divide 6 by numbers such as 1, 2, 3, or 6 itself.
divide both numbers by their common factor (5). 15 divide by 5 is 3 25 divide by 5 is 5 So...... 3 over 5
Same as average. For example, if you have 5 numbers, add them all up, then divide the result by 5. If you have 10 numbers, you add and divide by 10, etc.
Just 1 and 5.
