Question

3.In a school, 5/8 of the students are girls. If there are 240 boys, find the number of girls in the school.​

Answer 1

GIVEN :

Fraction of girls in the school = 5/8

Number of boys in the school = 3/8 = 240

Let the total number of students in school be x

3/8 of x = 240

3/8 × x = 240

x = 240 × 8/3

x = 80 × 8

x = 640

Total number of students in school = 640

Number of girls in school = Total Students in school - number of boys

= 640 - 240

= 400

Therefore, there are 400 girls in the school.

Answer 2

Answer:

400

Step-by-step explanation:

Let the total number of students be x.

Boys=240

Girls=5x/8

Total students=240+5x/8

x=240+5x/8

x-5x/8=240

3x/8=240

x=240*8/3

x=640

Girls=5x/8

5*640/8

400

THERE ARE 400 GIRLS.
