Answer 1

Add them together and divide by 7

Answer 2

I understand that the answer is 4 6/7 but how can I break it down to understand how I got the answer. I know that I have to sum all of the values and divide them by the number of values in order to get the answer but I'm not understanding how the 6/7 came into place?

Answer 3

\[\frac{8+7+7+5+3+2+2}{7}=\frac{34}{7}=4 \frac{6}{7}\]

Answer 4

I did add them and got 34 divided by 7=4

Answer 5

34 divided by 7 is NOT 4
