Answer 2

Answer:

Step-by-step explanation:

Total no of students = 720

No of students like maths = 280

No of students like science = 320

No of students like drawing = 720-[280+320] = 120

i] No. of students like maths to no. of students like science.

280:320

=7:8

ii] No. of students like drawing to total no. of students

120:720

=1:6

iii] No. of students like science to no. of students like drawing.

320:120

=3:8

iv] No. of students like maths to total no of students.

280:720

=7:18
