Question

ln co educational school, 45% students are girls. lf there are 440 boys in school , find. the number of girls in the school​

Answer 1

Answer:

360

Step-by-step explanation:

In the school, 45% students are girls. This must mean that 100%-45%=55% are boys.

Let the total number of students be $x$.

55%⇒55 out of 100 = $\frac{55}{100}$

$\frac{55}{100}$ × $x$ = 440

$x$ = 440 × $\frac{100}{55}$

$x$ = 8 × 100

  = 800

If there are 800 total students out of which 440 are boys, the number of girls must be 800-440=360.

Answer 2

Step-by-step explanation:

let the total no. of student be x

55% of x = 440

55/100 × x = 440

x= 440*100/55

x=800

total no. of student = 800

no. of girls = total no. of student- no. of boys

no. of girls = 800-440

360
