Answer 1

There are 198 girls in the school

Answer 2

Let the number of students be x.

Given that 45% of the total students are girls. there are 440 boys in the school.

⇒ 45% of x + 440 = x

⇒ (45/100) * x + 440 = x

⇒ 45x + 44000 = 100x

⇒ 55x = 44000

⇒ x = 44000/55

⇒ x = 800.

So, total number of students = 800.

Now,

⇒ Number of girls = 45% of x

                              = 45% of 800

                              = (45/100) * 800

                              = 45 * 8

                              = 360.

Therefore, the number of girls in the school = 360.

Hope this helps!
