1000-356=<<1000-356=644>>makgetlho a le 644
1000-135=<<1000-135=865>>makgetlho a le 865
644+865=<<644+865=1509>>makgetlho a le 1509
####  makgetlho a le 1509 

There are 4 x 18 = <<4*18=72>>72 seats in the school auditorium.
72 x1/4 = <<72*1/4=18>>18 seats were occupied by the administrators.
There were 72 - 18 = <<72-18=54>>54 seats not occupied by the administrators.
54 x 1/3 = <<54*1/3=18>>18 seats were occupied by the parents.
So, 54 - 18 = <<54-18=36>>36 seats were occupied by the students.
