Answer 2

Given:

Number of students in a class = 180

Number of girls in a class = 75

To Find:

The ratio of the girls to the number of boys

Solution:

To find the number of boys in a class, we will subtract the number of girls in the class from the number of students in a class.

⇒ Number of students in a class - number of girls in a class = number of boys in a class.

⇒ 180 - 75 = 105

So, the number of boys in a class is 105.

Now, to find the ratio of boys to girls in a class. We will divide 75 and 105 by 15.

We get, 5/7

Which is 5:7 in ratio.

Therefore, the ratio of boys to girls in a class is 5:7.
