The document describes a science fair that will be held in an auditorium for three middle schools - Hart, Malcolm, and Kennedy. The space allocated to each school in the auditorium should be proportional to the number of students enrolled in each school, with Hart having about 1,000 students, Malcolm having about 600 students, and Kennedy having about 400 students. Students are asked to divide a rectangle representing the auditorium to show the space each school should receive based on enrollment, and to calculate the fraction and percentage of total space and costs each school should be allocated.
