Answer 1

Answer:

1) 8,          2) 16,         3) 2/5

Step-by-step explanation:

1) The number of students who like to study English are:
40*1/5 = 1*8 = 8
So, a total of 8 students like to study English.

2) The number of students who like to study Maths are:

40*2/5 = 2*8 = 16
So, a total of 16 students like to study Maths.
3) The fraction of students who like to study Science is:

40-16-8 = 16

40*x/5 = 16

40x = 16*5

x = 80/40

x = 2

So, a 2/5 of the total students like to study Science.

Hope it helped :)
