Solution

Given, number of teachers = 102

Number of students = 3300

The ratio of number of teachers to that of students

= $\frac{N u m b e r o f t e a c h e r s}{N u m b e r o f s t u d e n t s}$

$= \frac{102}{3300} = \frac{17}{550} = 17 : 550$ [Dividing numerator and denominator by HCF of 102 and 3300 i.e. 6]
