Question

There are 4 girls and 8 boys taking a swimming lessons write the ratio that compares the number of girls taking swimming lessons to the total number of students taking swimming lessons

Answer 1

The ratio that compares the number of girls taking swimming lessons to the total number of students taking swimming lessons is
`(no. of girls)/(total no. of students)=(1)/(3)`.

Explanation:

It is given in the problem that there are 4 girls and 8 boys taking a swimming lessons.

Calculate the total number of students taking swimming lessons.

Total number of students= number of girls + number of boys

Put number of girls= 4 and number of boys= 8.

Total number of students= 4 + 8

= 12

Write the ratio that compares the number of girls taking swimming lessons to the total number of students taking swimming lessons.

`(no. of girls)/(total no. of students)=(4)/(12)`

`(no. of girls)/(total no. of students)=(1)/(3)`

Therefore, the ratio that compares the number of girls taking swimming lessons to the total number of students taking swimming lessons is
`(no. of girls)/(total no. of students)=(1)/(3)`.

Answer 2

The ratio comparing Number of girls to the total number of student is 1/3

Explanation:

Given :

4 girls and 8 boys ,

Total students=12.

To find :

Ratio of girls with respect to the total swimming class?

Solution:

Now for calculating ratio we should know ,

the required fraction .

So required fraction for girls can be written as :

ratio of girls=No of girls in classes/Total No of student.

total students=No of girls +No of boys=4+8=12.

Total students=12.

Now, No of girls presented=4.

Required Ratio=4/12

=1/3.

Hence the ratio of girls to the total number of student is 1/3.

It say that there 1/3 girl presented in swimming class or 1/3 of class is of girls.
