Answer» Answer: no.of students were PRESENT in the class = 40 (1)no.of students like to study Mathematics = 1/5 of total i.e., 1/5×40 = 8 students (2)no.of students like to study ENGLISH = Sum of students like MATHS and computers(8+16) = 24 - Remaining students(40-24=16),if all remaining students like English i.e.,16 students. (3)Fraction of total no.of students like to study Computers = 2/5 or 16 students(in decimal form that is 0.4) |
