Question

In a class of 60 students, on average, 6 will be left handed. if a class includes 27 lefties , estimate how many students are in the class.

Answer 1

Since 6 is 10% of 60, if we assume that 10% of the class are left handed and there are 27 left handed students, then 27 is 10% of the total amount of students in the class.

To find how many students are there in the class, notice that 27 is 10% of 270.

Therefore, we can estimate that the total amount of students in that class, is:

$270$
