Question

In a school A, the ratio of number of teachers to number of students is 3 : 13 while in school B. the ratio of number of teachers to students is 4: 11. In which school is the total number of students greater?​

Answer 1

Answer:

School B

Step-by-step explanation:

First, we find the LCM of the denominators which is 143.

We do this to attain a common denominator.

Now,in school A, ratio

= 3:13 or 3*11:13*11

=33:143

Now in school B, ratio

= 4:11 or 4*13:11*13

= 52:143

Now clearly, 52>33

so, we can say that no. of students in school B> no. of students in school A
