Given

Total number of students = 4320

Number of girls = 2300

The number of boys = 4320 - 2300

= 2020

So,

the ratio of

(a) Number of girls to the total number of students:

$=\frac{2300}{4320}=\frac{230}{432}=\frac{115}{216}=115:216$

(b) The number of boys to the number of girls:

$=\frac{2020}{2300}=\frac{101}{115}=101:115$

(c) The number of boys to the total number of students:

$=\frac{2020}{4320}=\frac{101}{216}=101:216$
