Since the current ratio of students to teachers is 16:1, that means that there are 16 students for every teacher. So if there are 480 students and we divide the number of students by the student teacher ratio, we will find the number of teachers.
480 divided by 16 yields 30 teachers. Indeed, 480/30 = 16:1
In order to change the ratio to 15 students to one teacher, we would multiply the number of teachers times the desired new ratio.
30 teachers times 15:1 yields a new student population of 450.
Since the ratio was decreased, the number of students actually went down!
Hope this helps,
