What is the total number of students in this class?

Question

Two thirds of students in a class study math and the remaining eight students do not study math. What is the total number of students in this class?

Answer 1

The students study maths  =  2/3

Remaining students  =  1 -  2/3

                                  =  (1/1)  - (2/3) 

Upon taking LCM of denominators

LCM of 1 and 3 is 3.

Remaining students  =  (3 - 2) / 3

                                  =   1/3

Given that the remaining stundents = 8

1/3 part  =  8

The students study maths  =  2/3

                                           =  2(1/3) 

                                           =  2(8)                    [Since 1/3 part  =  8]

                                           =  16

Total Students  =  8 + 16

Total Students  =  24

Answer :

Total Students  =  24
