Find the ratio of the following.

(a) Speed of a cycle 15 km per hour to the speed of scooter 30 km per hour.

(b) 5 m to 10 km

(c) 50 paise to Rs 5

(a) Given that, Speed of cycle = 15 km/hr

Speed of scooter = 30 km/hr

Hence ratio of speed of cycle to that of scooter = 15 : 30 = 1 : 2

(b) Required ratio = 5 : (10×1000) (∵ 1 km = 1000 m)

= 1 : 2000

(c) ∵ 1 Rs = 100 paise

∴ Required ratio = 50 : 500

= 1 : 10
