in a class of 40 children 3/8 likes english,2/5 likes maths and 3/4 like science .find the number of children who like each subject.
No one likes those subjects. They are all lying. (Just kidding!)
English: 40*(3/8) = 15 students out of 40 likes it.
Math: 40*(2/5) = 16 students out of 40 likes it.
Science: 40*(3/4) = 30 students out of 40 likes it.
