Question

In a college out of 4320 students, 2300 are girls find the ratio of<br />1. no of girls to the total no of students<br />2. no of boys to the no of girls​

Answer 1

Answer:

The ratio of the number of boys to the number of girls is  101 : 115

Step-by-step explanation:

It is given that,

Total number of students = 4320

The number of girls = 2300

∴ The number of boys = (4320-2300)

                                     = 2020

So, the number of boys is 2020.

∴ The ratio of the number of boys to the number of girls_

2020 : 2300

= 2020/2300 (dividing by 10)

= 202/230 (dividing by 2)

= 101/115 (there is no common factor of 101 and 115 except 1)

= 101:115

∴ The ratio of the number of boys to the number of girls is  101 : 115.

Answer 2

Answer:

Given,

      Total No. of Students: 4320

      No. of Girls                 : 2300

(1)  

$2300 : 4320\\\\= \frac{2300}{4320}\\ \\= \frac{115}{216} \\\\= 115 : 216$

(2)

$4320 - 2300 = 2020\\\\\\2020:2300\\\\= \frac{2020}{2300}\\\\=\frac{101}{115}$
