2.1cm to 1.2cm=2.1cm/1.2cm=21/12=7:4 60paisa to 4rupees, 1rupee=100paisa =>4rupee=4*100=400paisa =>60paisa/400paisa=3:20 15mm to2cm, 1cm=10mm,therefore,2cm=2*10=20mm So,15mm/20mm=3:2 1/15:1/25=1/15/1/25, taking reciprocal it will be, 1/15*25/1=5/3=5:3 Total no. Of students=30+25=55 1)30/25=6/5=6:5 2)25/55=5/11=5:11 3)30/55=6/11=6:11 Hope so it has helped you.
