Question

If the ratio between students to female adults is 7:6 while female adults to male adults is 4:1. What is the ratio of students to male adults?

Answer 1

Answer: 14:3

Step-by-step explanation:

Given

Ratio between students(s) to female(f) adults is 7:6

while ratio between female(f) to male(m) is 4:1

So, we can write

$\Rightarrow \dfrac{s}{f}=\dfrac{7}{6}\quad \ldots(i)$

Also, we can write

$\Rightarrow \dfrac{f}{m}=\dfrac{4}{1}\quad \ldots(ii)$

Multiply both equations

$\Rightarrow \dfrac{s}{f}\times \dfrac{f}{m}=\dfrac{7}{6}\times \dfrac{4}{1}\\\\ \Rightarrow \dfrac{s}{m}=\dfrac{14}{3}$

So, the ratio of the students to male adults is 14:3 .
