उत्तर
(i) orange : Yellow = 8 : 4 = 2 : 1
(ii) green : blue = 3 : 9 = 1 : 3
(iii) green : orange = 3 : 8
orange : green = 8 : 3
blue : orange = 9 : 8
orange : blue = 8 : 9
green : yellow = 3 : 4
yellow : green = 4 : 3
blue : yellow = 9 : 4
yellow : blue = 4 : 9
green : blue = 3 : 9 = 1 : 3
blue : green = 9 : 3 = 3 : 1
yellow : orange = 4 : 8 = 1 : 2
orange : yellow = 8 : 4 = 2 : 1
