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

$\mathrm{Fraction}\mathrm{of}\mathrm{the}\mathrm{total}\mathrm{students}\mathrm{who}\mathrm{like}\mathrm{to}\mathrm{study}\mathrm{science}=\frac{16}{40}=\frac{2}{5}$
