• # question_answer 9) There are 102 teachers in a school of 3300 students. Find the ratio of the number of teachers to the number of students.

Given, number of teachers = 102 and number of students = 3300 $\therefore$ Required ratio of teachers to the number of students $\text{=}\frac{\text{Number}\,\text{of}\,\text{teachers}}{\text{Number}\,\text{of}\,\text{students}}=\frac{102}{3300}$ $\because$$102=2\times 3\times 17$and$3300=2\times 3\times 2\times 5\times 5\times 11$ $\therefore$HCF of 102 and $3300=2\times 3=3=\frac{102+6}{3300\div 6}=\frac{17}{550}=17:550$
