12oo students attend a school the ratio of teachers to students is 1 : 30 . How many teacher
x/1200 = 1/30
30x = 1200
x = 40
To determine the number of teachers in a school with 1200 students and a teacher-student ratio of 1:30, you can use the following steps:
1. Understand the ratio: The given ratio, 1:30, represents the comparison between the number of teachers and the number of students. It means that for every one teacher, there are 30 students.
2. Calculate the number of teachers: To determine the number of teachers, you need to divide the total number of students by the number of students per teacher. In this case, you would divide 1200 students by 30 students per teacher.
1200 students รท 30 students per teacher = 40 teachers
Therefore, there are 40 teachers in the school with 1200 students.
