Total number of students in school = 4320
Number of girls = 2300
Therefore, number of boys = 4320 – 2300 = 2020
(a) Ratio of girls to total number of students = 2300/4320 =115/216 = 115 : 216
(b) Ratio of boys to that of girls = 2020/2300 = 101/115 = 101 : 115
(c) Ratio of boys to total number of students = 2020/4320 = 101/216 = 101 : 216
