It would be 6/7. Because first you would add 5+5+7+5+9+11+18 which equals 60. After that, you would divide 60 to 7. You should get 6/7. I hope this helped you!

When someone says to find the mean of a group of numbers, it usually means to take the average of the set of numbers.

Add up all the numbers together.

5 + 5 + 7 + 5 + 9 +11 + 18 = 60

Then divide by the number of elements in the set of numbers.

In this case, it is 7.

60 / 7 = 8 4/7

So, the average for that set of numbers is 8 4/7.
