(a) Speed of a cycle 15 km per hour to the speed of scooter 30 km per hour.Given, Speed of cycle = 15 km per Hour & Speed of Scooter = 30 km per hour Ratio = (๐๐๐๐๐ ๐๐ ๐๐ฆ๐๐๐)/(๐๐๐๐๐ ๐๐ ๐ ๐๐๐๐ก๐๐) = 15/30 = 1/2 = 1 : 2 Ex 8.1, 1 Find the ratio of the following. (b) 5 m to 10 kmRatio = (5 ๐ )/(10 ๐๐) = (5 ๐)/(10 ร 1000 ๐) = 1/2000 = 1 : 2000 (1 km = 1000 m) Ex 8.1, 1 Find the ratio of the following. (c) 50 paise to Rs 5 Ratio = (50 ๐๐๐๐ ๐)/(5 ๐๐ข๐๐๐๐ ) = (50 ๐๐๐๐ ๐)/(5 ร 100 ๐๐๐๐ ๐) = 1/10 = 1 : 10 (Rs 1 = 100 paise)
