Answer 2

Step-by-step explanation:

Total number of students in the class = 40.

(i) Of these 1/5 of the total number of students like to study English.

Thus, the number of students who like to

study English = 1/5 of 40

= 1/5 x 40 = 8 students.

(ii) 2/5 "of" 40 = 2/5 x 40 = (2 x 40)/5 =

80/5=16 Students.

(iii) The number of students who like English and Mathematics = 8 + 16 = 24.

Thus, the number of students who like Science 40 - 24 = 16.

Thus, the required fraction is `16/40`.
