Answer 1

Answer:

let the no of boys and girls be 5x and 3x

so

5x+3x = 720

8x= 720

X= 720/8 = 90

no of boys = 5*90= 450

no of girls = 3*90=270

Answer 2

Answer:

5:3=720

let the common factor = x

boys =5x

girls = 3x

5x+3x=720

8x=720

x=720/8=90

therefore boys =5*90=450

girls =3*90=270
