a= 14 , b= 15, c =15 , d =18 , e= 18.

Step-by-step explanation:

Stratified sample is a sampling technique used to show the participation of each group present in the population..

Person sampled from each group =

Total students = 140+150+150+180+180 =800

In sample

Person of Year 7 students =

Person of Year 8 students =

Person of Year 9 students =

Person of Year 10 students =

Person of Year 11 students =

Hence, a= 14 , b= 15, c =15 , d =18 , e= 18.

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an
