Answer 2

Answer:

1)18

2)9

3)18

4)2/5

5)1:2

Step-by-step explanation:

Total students =45

2/5 of the total number like to study English =2/5 × 45

E = 18

1/5 of the total number like to study Mathematics,

M= 1/5× 45

M=9

Social science, S= 45-(E+M)

S = 45-(18+9)

S = 45-27

S= 18

social science =18

that means,

18/45= 2/5

ratio of students,

M:E =8:18 =1:2
