Question

The ratio of boys to girls in Fiona's class is

1 to 3. There are 24 students in the class.
How many of the students are girls?

Answer 1

Explanation:

Given,

The ratio of boys to girls in Fiona's class is 1:3

The total student in the class is 24

To find,

how many students are girls

Solution,

It is clear that the total number of boys and girls is 24

i.e., boys + girls=24 ------ (equation 1)

Let the ratio be in the terms of x

Consider boys ratio as x

And the girl's ratio as 3x

Now as per the equation 1,

x + 3x= 24

4x= 24

x= 6

Hence, Boys (x)= 6

And Girls (3x)= 3× (6)= 18

You can verify it by adding 6+18= 24
