Answer:

There are 6 girls more than boys.

Step-by-step explanation:

Given,

Ratio of boys to girls is 2 : 3.

Let the NUMBER of boys be 2a and number of girls be 3a.

In class,

⇒ Number of students = number of boys + number of girls

⇒ 30 = 2a + 3a { given, total = 30 }

⇒ 30 = 5a

⇒ 30 / 5 = a

⇒ 6 = a

There are 3a - 2a girls more than boys, so number of girls( extra ) is 3a - 2a = a = 6( from above ).
