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

(b) Number of boys to the number of girls.

(c) Number of boys to the total number of students.

Answer :

Total number of students = 4320

Number of girls = 2300

Number of boys = 4320 – 2300 = 2020

(a) Ratio of number of girls to the total number of students

= \(\frac{2300}{4320} = \frac{2300÷20}{4320÷20} = \frac{115}{216} \)

= 115 : 216

(b) Ratio of number of boys to the number of girls
= \(\frac{2020}{2300} = \frac{2020÷20}{2300÷20} = \frac{101}{115} \)

= 101 : 115

(c) Ratio of number of boys to the total number of students

= \(\frac{2020}{4320} = \frac{2020÷20}{4320÷20} = \frac{101}{216} \)

= 101 : 216
