How Many Classrooms are Needed for 3210 Students?

What is the ratio of classrooms to students?

The ratio of classrooms to students is 1:15.

How many classrooms are needed if 3210 students enrolled in the first semester?

A. 200 classrooms

B. 210 classrooms

C. 214 classrooms

D. 218 classrooms

Answer:

The correct answer is C. 214 classrooms.

To find the number of classrooms needed if 3210 students enroll in the first semester, we can use the ratio of classrooms to students which is 1:15. This means that for every 15 students, 1 classroom is needed.

We can set up a proportion to solve for the number of classrooms:

1 classroom / 15 students = x classrooms / 3210 students

Cross multiplying, we get:

15 * x = 1 * 3210

x = 3210 / 15

x = 214

Therefore, 214 classrooms are needed if 3210 students enroll in the first semester.
