Answer 2

Answer:

1. 7/8

2. 8/15

3. 7/15

Step-by-step explanation:

1. Here no.of girls=80

  Total no.of students=150

Then,

  No.of boys=150-80=70

Ratio of boys to girls=no.of boys/no.of girls

                                  = 70/80=7/8

2. no.of girls/total no.of students

   =80/150

    =8/15

3. no.of boys/total no.of students

   =70/150

   =7/15
