Answer 2

Ratio gives an interger comparison of items with respect to the total, Hence,the number of girls in the gathering is 8

Given that:

Ratio of boys to girls = 3 : 2

• Boys ratio = 3

• Girls ratio = 2

• Sum of ratios = (3 + 2) = 5

The number of girls can be calculated thus :

Let total Number of students = s

3/5 × s = 12

3s = 12 × 5

3s = 60

s = 60 / 3

s = 20

Number of girls = 2/5 × 20

Number of girls = 8
