If the student ratio in a school is 12:1 and there are 1500 students/teachers total how would you find out how many students there are and how many teachers?

If there are 12 times as many students as teachers, then there are 13 times as many students and teachers as there are teachers alone. To find the number of teachers, you divide 1500 by 13 to get 115 teachers. The number of students then is 1500 - 115 or 1385 students.

Imagine that you were setting up groups of students and teachers so that there were 12 students and 1 teacher for each group. This would keep your 12:1 ratio. If there are 1500 total people, with 13 people per group, how many groups would there be? There is one teacher for each group, so the number of groups is also the number of teachers. There are 12 students for each teacher, so multiply the number of teachers by 12 to find the number of students.

s/t = 12
s+t=1500
from these two equations you can get your answer.
