in a class there are 17 right handed students and 3 left handed students, what fraction of the class is left-handed?

20 students (17+3)

3 left-handed

3/20 are left-handed

To find the fraction of the class that is left-handed, we need to divide the number of left-handed students by the total number of students in the class.

In this case, we have 17 right-handed students and 3 left-handed students. Therefore, the total number of students in the class is 17 + 3 = 20.

To find the fraction, we divide the number of left-handed students (3) by the total number of students (20):

Fraction of left-handed students = 3 / 20.

So, the fraction of the class that is left-handed is 3/20.
