6+8+7= 21 21/3 = 7 The average is 7.
6.
3+7+2+8+10 = 30 30 ÷ 5 = 6 Average = 6
8+9+6 = 23 23/3 = 7 and 2/3
5.75
Sum = 36 Count = 6 Average = Sum/Count = 36/6 = 6
5 2/5

6 + 7 + 8 = 21 there are three numbers so divide by three 21/3 = 7
It is: 8+7+7+5+3+2+2 = 34/7 => 4 and 6/7 which is the average mean
