Answer» (i) 72 : 60 = 7260 =72÷1260÷12 =65 = 6 : 5 (HCF of 72 and 60 = 12)Thus, the reduced form of 72 : 60 is 6 : 5.(ii) 38 : 57 = 3857 =38÷1957÷19 =23 = 2 : 3 (HCF of 38 and 57 = 19)Thus, the reduced form of 38 : 57 is 2 : 3.(iii)52 : 78 = 5278 =52÷2678÷26 =23 = 2 : 3 (HCF of 52 and 78 = 26)Thus, the reduced form of 52 : 78 is 2 : 3. |
