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.
(a) It is given in the question that,
Total number of students = 4320
Number of girls = 2300
Therefore,
Number of boys = 4320 – 2300
= 2020
Therefore,
Required ratio = 
= 
= 
(b) It is given in the question that,
Number of girls = 2300
Number of boys = 2020
Therefore,
Required ratio = 
= 
= 
(c) We have,
Total number of students = 4320
Also,
Number of boys = 2020
Therefore,
Required ratio = 
= 
=
