Question

in a college, there are 4320 students. Out of them, 2300 members 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.
(Hint: Out of 4320, 2300 members are girls. Rest of them are boys).​

Answer 1

Step-by-step explanation:

Total no of students = 4320

total no of girls = 2300

total no of boys = 4320 - 2300 = 2020

a) no. of girls/no of students = 2300/4320 = 115/216

b) no. of boys/no of girls = 2020/2300 = 101/115

Hope, it is helpful

Answer 2

$\huge\mathcal{\underline{\green{Answer:}}}$

(a) 115:216

(b) 101:115

Step by step explanation:

Total no. of students = 4320

No. of girls = 2300

∴ No. of boys = 4320 - 2300

⠀⠀⠀⠀⠀⠀⠀⠀⠀= 2020

(a) No. of girls to the total no. of students

$\rightarrow$ 2300:4320

$\rightarrow$ $\frac{2300}{4320}$

$\rightarrow$ $\frac{115}{216}$

$\rightarrow$ 115:216 ans.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

(b) No. of boys to the no. of girls

$\rightarrow$ 2020:2300

$\rightarrow$ $\frac{2020}{2300}$

$\rightarrow$ $\frac{101}{115}$

$\rightarrow$ 101:115 ans.

Therefore, Answer = (a) 115:216 & (b) 101:115
