Question

There are 30 students in a class how many of them are girls with the ratio 2:3

Answer 1

Step-by-step explanation:

Total = 30 students

Ratio = 2:3

Let x be the number of girls.

If ratio of girls to boys is 2:3,

x/30 = 2/(3+2)

x = (2×30)/5

x = 12

Therefore, there are 12 girls in the class.

If ratio of boys to girls is 3:2,

x/30 = 3/(2+3)

x = (3×30)/5

x = 18

Therefore, there are 18 girls in the class.
