Answer 1

Answer:

students who like to study science=16

fraction of students who like science=2/5

Step-by-step explanation:

no of students=40

English = 1/5

no if students who like to study English=(1/5)×40=8 students

Maths=2/5

no if students who like to study English=(2/5)×40=16 students

therefore

no of students who like to study science=40-(16+8)=16

so

fraction of students who like science=16 = 2/5

40
