Question

There are 15,301 students in a school district. The district keeps class sizes at 21 students per teacher. How many teachers will the school district need? Explain.

Answer 1

To calculate the number of teachers needed for 15,301 students with a 21 student-to-teacher ratio, divide the total number of students by the ratio and round up to the nearest whole number, resulting in 729 teachers required.

Step-by-step explanation:

The question asks us to calculate how many teachers the school district will need if there are 15,301 students and the district maintains a ratio of 21 students per teacher. To find the answer, we divide the total number of students by the number of students per teacher, which is 15,301 ÷ 21. This calculation gives us approximately 728.619, but since we cannot have a fraction of a teacher, we round up to the nearest whole number because even one extra student will require a full teacher. Therefore, the school district will need 729 teachers.
