Add all the numbers and divide by their count:
34/7 = 4 6/7
Work:
(8+7+7+5+3+2+2)/7 = 34/7 = (28 + 6)/7 = 28/7 + 6/7 = 4 + 6/7= 4 6/7
Explanation:
sum of all the numbers: 8+7+7+5+3+2+2 = 34
number count: 7
fraction looks like: 34/7
the highest number that gives the integer, when divided by 7: 28
reminder: 34-28 = 6
------
Check:
4 6/7 = (4*7 + 6)/7 = (28 + 6)/7 = 34/7
Done!

To find the average (mean) you must add the seven numbers, and then divide that by 7.
8+7+7+5+3+2+2 = 34
Divide that by 7, and you get 34÷7
Now 7 goes into 34 four times (which gives you 28), so there is 6 left over. So 34/7 = 4 6/7.

8+7+7+5+3+2+2=34
34/7=4 with a remainer of 6 which is 6/7 for a total of 4 6/7.

The average is 34/7.. And if you don't an improper fraction make it a mixed fraction by dividing 34/7 which is 4 6/7.

8+7+7+5+3+2+2 = 34
34 divided by 7 is 34/7 or 4.857
6/7 equals .857 , or 4 6/7 = 4.857
