Question

A class of 25 students includes 12 boys. Does the ratio of girls to students represent a fraction? Does the ratio of boys to girls represent a fraction? How do you know?

Answer 1

Number of Girls:Number of Students = 13:25

Number of Boys:Number of Girls = 12:13

Explanation:

We are given the following information in the question:

Total number of students in class = 25

Number of boys in the class = 12

Number of girls in the class =

`\text{Total number of students - Number of boys} = 25 - 12 = 13`

Now, we have to find ratio of number of girls to number of students:

Number of Girls:Number of Students = 13:25 =
`(13)/(25)`

There are 13 girls to every 25 students.

We have to find ratio of number of boys to number of girls:

Number of Boys:Number of Girls = 12:13 =
`(12)/(13)`

There are 12 boys to every 13 girls.

Yes, these ratios are fraction because ratio help us compare two things.
