He ratio of girls to boys in a classroom is 3: 5. kevin says there must be 8 students in the classroom. which explains whether kevin is correct? kevin is correct because 3 girls + 5 boys = 8 students. kevin is correct because 5 girls + 3 boys = 8 students. kevin is incorrect because 3: 5 may be a simplified ratio. kevin is incorrect because the ratio 3: 5 does not compare different units.

Kevin is correct because 3 girls + 5 boys = 8 students.

The correct option is:

The ratio of the number of girls and number of boys in a classroom are:

                      3:5

Now, kevin says that:

The total number of students in the classroom must be 8.

This means that if there would be 3 girls and 5 boys then the ration of boys and girls will be: 3:5 and also the total number of students in the classroom will be:

Number of girls+ Number of boys

=  3+5=8 students
