$\huge\bigstar\underline\mathfrak\blue{Explanation}$

Given : Number of boys = 240

Number of girls = 260

______________________

a). The ratio of the number of girls to the number of boys :

=> 260 : 240

=> 13:12 ( required ratio )

______________________

b). Firstly, we have to find the total number of pupils

=> Number of girls + number of boys = Total number of pupils in the school.

=> 260 + 240 = 500

Therefore,

total number of students = 500

_____________________

Now, The ratio of the number of boys to the total number of pupils in the school :

=> 240 : 500

=> 12 : 25 ( required ratio )

Answer 2

first segment:

The ratio of the number of girls to the number of boys :

=260 : 240

=13:12

2nd segment:

No.of girls + no.of boys = Total number of students

=260 + 240 = 500

total number of students = 500

ratio of the number of boys to the total number of pupils in the school :

=240 : 500

=12 : 25
