## Task 7

In the kindergarten group of class 3a, there are 18 students. In the afternoon, they play outside. One third of the students play with the ball, one sixth climb the climbing frame, and one half play hide and seek.

How many children are not occupied?
The 3rd part consists of 6 students, the 6th part 3 students, and the 2nd part 9 students. Since $6+3+9=18$, no child is left unoccupied.
