Question

In a class of 40 students on average 4 will be left handed if a class includes 6 lefties estimate how many students are in the class

Answer 1

If on average 4 out of 40 students are left-handed, we can express this as a ratio of left-handed students to right-handed students:

left-handed students : right-handed students = 4 : 36

Simplifying this ratio by dividing both sides by 4, we get:

1 : 9

This means that for every 1 left-handed student, there are 9 right-handed students in the class.

If we know that there are 6 left-handed students in the class, we can use this ratio to estimate the total number of students in the class:

left-handed students : right-handed students = 1 : 9
6 : 54

Therefore, we can estimate that there are 6 + 54 = 60 students in the class.
