9+12/10=9.2

Hope that helps

Answer 2

The answer is 9.2

Explanation:

Total number paintings made by 7 children =
`7*8=56`

Total number of paintings made by the remaining 3 children (10-7) =
`3*12=36`

Therefore, total number of paintings =
`56+36=92`

Hence, average number of paintings by all the 10 children =

`(92)/(10)` = 9.2

So, the average number of paintings made by children at the art camp is 9.2.
