In a college, out of 4320 students, 2300 are girls. Find the ratio of
(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 1

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