Question 281990
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
