Out of 38students in class third, only 17 students were present. What fraction of the students were absent

17 present means 21 absent.

So, what fraction is that?

What is the ratio of cups of cereal to cups of chocolate chips? What type of ratio is this?

To find the fraction of students who were absent, we need to subtract the number of students who were present from the total number of students in the class.

Total number of students in class third = 38
Number of students present = 17

To find the number of students absent, we subtract the number of students present from the total number of students:

Number of students absent = Total number of students - Number of students present

Therefore,

Number of students absent = 38 - 17 = 21

So, out of the 38 students in class third, 21 students were absent.

To find the fraction of students who were absent, we divide the number of students absent by the total number of students:

Fraction of students absent = Number of students absent / Total number of students

Fraction of students absent = 21 / 38

Therefore, the fraction of students who were absent is 21/38.
