Question

In a class of 40 28 passed their maths test what fraction of the class passed

Answer 1

Unsimplified: 28/40 people passed

Simplified: 7/10 people passed

Explanation:

28/40 passed now we simplify it, divide both sides by two

28/4=7

40/4=10

7/10

Answer 2

The fraction of the class that passed the maths test is
`(7)/(10)`

Solution:

In the given question we know that the total number of students in the class is 40.

The class was given a maths test in which only 28 students passed and the remaining students failed.

So the to find out what fraction of the class passed the maths test, we need to divide the number of students that passed the maths test by the total number of students present in the class.

So we can write it as follows:

`(28)/(40)`

This fraction is not in the simplest form. To bring it to the simplest form we have to divide the numerator and denominator by 4.

This gives us:

`(7)/(10)`

As the fraction cannot be further reduced, this is the final answer.

Therefore the fraction of students that passed the maths test is
`(7)/(10)`
