Answer 2

The required ratio is 2:5.

Given:

Students appearing for exam=100

Students passed=60

To find:

The ratio of the number of students who failed to the total number of students​

Solution:

We can obtain the number of students who failed by subtracting the number of students who passed from the total number of students.

So, the number of students who failed=Total students-Students passed

=100-60

=40

Now, the required ratio=Students failed: Total students

Using values,

=40:100

=4:10

=2:5

Therefore, the required ratio is 2:5.
