Question

2/9 of a school population are teachers.if total population of the school is 729.find the number of students​

Answer 1

Answer:

Number of students = 567

Step-by-step explanation:

Given :

$\rm{Fraction\:of\:teachers\:in\:school=\dfrac{2}{9}}$

Total population of the school = 729

To find :

The numbers of the students in the school

Taken :

To find the number of students in the school use this equation -:

$\boxed{\sf{N=729-(\dfrac{2}{9}\times729)}}$

Where,

N = Number of students in the school

Here , first we will get the number of teachers . After that we have to subtract it with the total population.

Solution :

$:\implies\sf{N=729-(\dfrac{2}{\cancel{9}}\times\cancel{729})}$

$:\implies\sf{N=729-(2\times81)}$

$:\implies\sf{N=729-162}$

$:\implies\sf{N=567}$

So , the number of students are 567 .
