Answer:

The fraction of male student who play sport is $\frac{3}{4}$

Step-by-step explanation:

Given as :

Out of the total number of students , the fraction of male = $\frac{2}{3}$ of total number of students

Let the total number of students = x

So, The fraction of male student = $\frac{2}{3}$ of x

I.e The fraction of male student = $\frac{2 x}{3}$

Again

The number of students who play sports = $\frac{1}{2}$ of total number of students

Or, The number of students who play sports = $\frac{1}{2}$ of x

Or, The number of students who play sports = $\frac{x}{2}$

Let The total number of male student who play sport = y

So, According to question

$\frac{2 x}{3}$ of y = $\frac{x}{2}$

I.e $\frac{2 x}{3}$ × y = $\frac{x}{2}$

or, y = $\frac{\frac{x}{2}}{\frac{2 x}{3}}$

∴ y = $\frac{3}{4}$

So, The total number of male student who play sport = y = $\frac{3}{4}$

Hence ,The fraction of male student who play sport is $\frac{3}{4}$ Answer
