You have to find the average of the two fractions. 4/7 + 5/7 = 9/7 (9/7) / 2 = 9/14 OR You can say 4.5/7 = 0.6428571428571... convert that to a fraction and reduce and you get 9/14

When there is an even number of data items the median is the mean average of the middle two. → median of {2, 3, 4, 5, 7, 9} = (4 + 5)/2 = 9/2 = 4.5

Well, darling, if you add 5, 7, and 9 together, you get 21. And since there are three numbers, you divide 21 by 3 to get an average of 7. So, the average of 5, 7, and 9 is 7. Hope that clears things up for you, sweetie!
6 is the average of 7,6,2, and 9 because 7+6+2+9=24, 24 divided by 4 is 6!
5.8
The average of 7, 8, 9, and 4 is 7.
The mean average is (7 plus 11) divided by 2 = 9
-9
You have to find the average of the two fractions. 4/7 + 5/7 = 9/7 (9/7) / 2 = 9/14 OR You can say 4.5/7 = 0.6428571428571... convert that to a fraction and reduce and you get 9/14
8+9+6 = 23 23/3 = 7 and 2/3

9*2 = 18
2 |9| is 9 and |7| is 7 so 9-7 is 2
When there is an even number of data items the median is the mean average of the middle two. → median of {2, 3, 4, 5, 7, 9} = (4 + 5)/2 = 9/2 = 4.5
