Answer 1

Answer:

a))=3:2

b)) =3:5

Step-by-step explanation:

Total no. of girls =50-30=20

a) Ratio of boys to number of girls=30/20

=3:2

b) Ratio of boys to total students =30/50

=3:5

Answer 2

Step-by-step explanation:

Total number of children in a class = 50

number of boys + number of girls = total

30 + no. of girls= 50

no. of. girls = 50 - 30 = 20.

ratio of no.of boys to no.of. girls = 30:20

= 3 × 10 : 2 × 10

10 gets cancelled on both sides we get

= 3 : 2

ratio of no.of. boys to total = 30 : 50

= 3 × 10 : 5 × 10

10 gets cancelled on both sides we get

3 : 5
