Question

1/6 of class students are above average,1/4 are average and rest are below average. if there are 48 students in class , how many students are below average in class​

Answer 1

Answer:

Step-by-step explanation:

If you take 1/6 +1/4 the answer obtained will be the fraction of students above average  and the average students i.e 1/6 +1/4=5/12.The total number of students in the class is 1 or in fraction, it can be written as 12/12 referring to the fraction we obtained above.hence 12/12 - 5/12 is 7/12.If you use  the relation that

                  if    48 no of students=   1

                 hence                      ?  =   7/12

you can cross multiply : 7/12 * 48 = 28

                                             1

hence the number of students below average is 28
