--------------------
Add the numbers
Then divide that sum by how many numbers you added.
----------------
average = (8+7+7+5+3+2+2) = 32/7 = 4 + 4/7

You can put this solution on YOUR website! add up all the numbers and divide by how many numbers there are in this case 7.
(8+7+7+5+3+2+2)/7=
34/7=
4 6/7
I added up the numbers 34 and divided by 7 and got 34/7
There are a couple ways to get the mixed number 4 6/7
35/7=5 right? which is 4 7/7 right?
so 34/7 is one less so it must be 4 6/7
another way to look at it.
......4
7 | 34
....-28
.......6
4 with 6 remainder means 4 6/7
BTW as a decimal 4 6/7 is 4.85
