= 30/90= 1/3

2nd= 400mm/15mm

= 400/15= 15 10/26

3rd = 55p/100p

= 11/20

4th = 500ml/2000ml

Answer 2

1.1.5hour=1.5×60=90.the ratio of 30 minutes to 1.5=30/90=1:3.

2.40cm :1.5cm=40cm :1.5×100cm since 1m=100cm=40:150=4:15.

3.1rupee=100paise , 55paise :100paise=11:20.

4.500ml to 2l, 1l =1000ml required ratio =500/2000=5/20=5/5×4=1:4.
