in a class of 40 students 1/5 of the students like to study english .2/5 of the total number like to study mathematics and the remaining students like to study science . what fraction of the total number of students like to study science.

Total students = 40

students who like to study English = 1/5 × 40 = 8

students who like to study Math = 2/5 × 40 = 16

students who like to study Science = 40 - ( 8 + 16 ) = 40 - 24 = 16 

Fraction of the total students who like to study science = 1640 = 25

  • 8

no of students in a class = 40

no of students like english = 40 x 1/5 = 8 students

no of students like miathematics =2/5 = 40 x 2/5 = 16 students

no of students like science = 5/5 - ( 2/5 + 1/5 ) = 5/5 -3/5 2/5 = 40 x 2/5 = 16 students

therefore 2/5 (16) students like science
