Answer 2

Answer:

4:7

Step-by-step explanation:

According to the question,

The number of boys in a class = 20

and the number of girls in a class = 15

Now,

we are to find the ratio of number of girls to the total number of students in the class.

We know that, the total number of students in the class = sum of the number of boys and girls

= 20 + 15

= 35

Hence, the ratio will be 20 : 35

= 4 : 7 (Answer)
