Number of students in a school =3300

Ratio of number of teachers to the number of students = Number of teachers / Number of students

Ratio of number of teachers to the number of students =1023300

Ratio of number of teachers to the number of students =2×3×172×3×550

There are 102 teachers in a school of 3300 students. Find the ratio of the number of teachers to the number of students. The ratio of the number of teachers to the number of students is 17:550.

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

Solution:

Number of teachers in the school = 102

Number of students in the school = 3300

The ratio of the number of teachers to the number of students =  Number of teachers in the school  / Number of students in the school

= 102 / 3300 Here,

The factors of 102 are 2 × 3 × 17 and the factors of 3300 is 2 × 2 × 3 × 5 × 5 × 11

Now, the HCF of 102 and 3300 is 2 × 3 = 6.

= (6 × 17) / (6 × 550)

= 17 / 550

Therefore, 17:550 is the resultant ratio of the number of teachers to the number of students.
