Question

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

Answer 1

Number of teachers = $102$

Numbers of students = $3300$

Now ratio is =$102:3300$

But the ratio is not in its simplest form so we convert it into the simplest form by dividing the ratio by their HCF.

HCF=Highest Common Factor

HCF$(102,3300)=6$

After dividing the ratio by $6$ we get

$\frac{102÷6}{3300÷6}=\frac{17}{550}$$=17:550$

Hence, $17:550$ is the required answer.
