To find the number of teachers required to maintain the student-to-teacher ratio of 16:1 with 2,000 students, we can use the ratio formula.
The ratio of students to teachers is 16:1, which means for every 16 students, there is 1 teacher.
To find the number of teachers, we can set up the equation based on the provided ratio:
\[ \text{Number of teachers} = \frac{\text{Number of students}}{\text{Ratio of students per teacher}} = \frac{2000}{16} \]
Calculating this:
\[ \frac{2000}{16} = 125 \]
Therefore, the number of teachers needed to maintain the 16:1 ratio with 2,000 students is 125.
The correct answer is D) 125.
