Q.9 There are 102 teachers in a school of 3300 students. Find the ratio of the number of teachers to the number of students.

Number of teachers in a school = 102
Number of students in a school = 3300
Ratio of number of teachers to the number of students \(\frac{102}{3300} = \frac{102÷6}{3300÷6} = \frac{17}{550} \)
= 17 : 550
