Analysis:
sum of the fraction of both students in the two classes = 4/5 + 9/10 =
LCM of the denominators which are 5 and 10 is 10
so the sum of both fractions = 8/10 + 9/10 = 17/10
The average = 17/10 /2 = 17/10 x 2 = 17/20
In conclusion, the average of the fraction of students on both classes is 17/20.

Answer: 78.6</h3>
Work Shown:

Multiply across the rows to form a third column. Example: 9*90 = 810 in the first row.

The values in the third column add to 810+1440+1050 = 3300
Divide this over the total number of people which is 9+18+15 = 42
The mean is 3300/42 =78.571 approximately which rounds to 78.6
