Question

Answer 1

Answer:

mark as brainliest

Step-by-step explanation:

let the total students be x

if 3/8 of x= 240 Girl's

then, 3x/8=240

3x= 8×240

x= 640

remaining number of boys= 640-240=400 boys

Answer 2

Answer:

400 BOYS

Step-by-step explanation:

Total no. of students in fraction = 8/8

No. of boys in fraction = 5/8

No. of girls in fraction = 8/8 - 5/8 = 3/8

Let the total no. of students in numbers be x.

3/8 of x = 240 (no. of girls in numbers)

x = 240 × 8/3

x = 80 × 8

x = 640

Total no. of students = 640

No. of girls = 240

No. of boys = 640 - 240

= 400
