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.
These numbers divide into 15 evenly: 1 3 5 and 15.
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
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
5 & 17
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.
1 and 5.
100
They are: 5, 7 and 11
add all the numbers up and count how many numbers there are then divide it2+3+5+7=17 count the numbers. 4 17 divide by 4 = 4.25
