Fraction of students that were absent = 1/2
Fraction of students that were present = 1/2
Fraction of students that went on field trip = 1/2 x 1/2 = 1/4
Fraction of students that stayed back = 1/2 - 1/4 = 1/4
Find the number of students in school:
1/4 of the school = 704
4/4 of the school = 704 x 4 = 2816
Answer: There are 2816 students in the school
