Question

The teachers: student ratio in a school is 1:21 if there are 24 teachers then how many students are there?

Answer 1

Answer:

Student–teacher ratio or student–faculty ratio is the number of students who attend a school or university divided by the number of teachers in the institution. For example, a student–teacher ratio of 10:1 indicates that there are 10 students for every one teacher. The term can also be reversed to create a teacher–student ratio.
