Question

In an auditorium 1/6 of the students are 5th graders,1/3 are fourth graders, and 1/4 of the remaining students are second graders. If there are 96 students in the auditorium , how many second graders are there ?

Answer 1

Fraction of second graders: (1/4)(1-1/6-1/3) = 0.125
Number of second graders: 0.125 x 96 = 12

Answer 2

1/3=2/6 so 2/6 +1/6=3/6 which =1/2 so 1/4 of 1/2 is 1/8 so 96 divided by 8=12
