Given:

There are 102 teachers in a school of 3300 students.

To do:

We have to find the ratio of the number of teachers to the number of students.

Solution:

The ratio of the number of teachers to the number of students $=\frac{102}{3300}$

$=\frac{2\times3\times17}{2\times3\times550}$

$=\frac{17}{550}$

The ratio of the number of teachers to the number of students is $17: 550$.
