Example : In a class of 40 student 1/5 of the total number of student like to study English.2/5 of the total number like to study Mathematics and the remaining student like to study Science.
(i) How many students like to study English?
(ii)How many students like to study Mathematics?
(iii) What fraction of the total number of student like to study Science?
Answer : (i) Students like to study English = 1/5 of 40 = (1/5)(40) = 8
Hence 8 students like to study English
(ii) 2/5 of 40 student like to study maths i.e. (2/5)(40) = 16
(iii) Remaining students = 1 – [ (1/5)+(2/5)] =1 – [3/5] = 2/5
so that 2/5 of 40 student like to study Science i.e. (2/5)(40) = 16
