Using proportions, it is found that 15 teachers will need to be hired to maintain the student : teacher ratio.
<h3>What is a proportion?</h3>
A proportion is a fraction of total amount, and the measures are related using a rule of three.
In this problem, the ratio means that 1 teacher is needed for 9 students. How many teachers are needed for 135 students?
The <em>rule of three</em> is:
1 teacher - 9 students
x teachers - 135 students
Applying cross multiplication:
15 teachers will need to be hired to maintain the student : teacher ratio.
