Final answer:

To find the number of students in the conference hall, we can use the student-teacher ratio of 9:1. By setting up and solving an equation, we determine that there are 180 students out of a total of 200 people in the hall.

Step-by-step explanation:

To find the number of students, we need to determine the ratio of students to the total number of people in the conference hall. Given that the student-teacher ratio is 9:1, we can set up the following equation:

Students/Total = 9/10

We can solve for the number of students by multiplying both sides of the equation by the total number of people. This gives us:

Students = (9/10) * Total

Substituting the given total of 200 into the equation, we get:

Students = (9/10) * 200 = 180

Therefore, there are 180 students in the conference hall.
