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 =\( \frac{2300}{4320}\)
\(=\frac{ 115}{216}\)
\(= 115:216\)
(b) Ratio of boys to that of girls \(= \frac{2020}{2300}\)
\(= \frac{101}{115}\)
\(= 101:115\)
(c) Ratio of boys to total number of students \(= \frac{2020}{4320}\)
\(= \frac{101}{216}\)
\(= 101:216\)
