Question

One day at central high 1/12 of the students were absent and 1/5 of those present went to field trip. If the number of students staying in school was 704 how many students are enrolled at central high

Answer 1

Say there are x students at Central High School. Then x/12 are absent, which means 11x/12 are not absent. Of those not absent, 1/5 go on a field trip, so 4/5 of them remain. (4/5)(11x/12) = 44x/60 are left in school.

44x/60 = 704
44x = 704 x 60 =42,240
x =42240/44= 960
