Arrange the following rational numbers in ascending order:

(i) (ii)


(iii) (iv)

(i)



And,



Since, the denominators of all the numbers are different therefore we will take LCM of the denominators.


LCM of 9, 12, 18 and 3 = 36






Clearly,


-24 < -16 < -15 < -14


Therefore,



Hence,



(ii)



And,



Since, the denominators of all the numbers are different therefore we will take LCM of the denominators.


LCM of 4, 12, 16 and 24 = 48






Clearly,


-36 < -21 < -20 < -18


Therefore,



Hence,



(iii)



Since, the denominators of all the numbers are different therefore we will take LCM of the denominators.


LCM of 5, 10, 15 and 20 = 60






Clearly,


-44 < -42 < -39 < -36


Therefore,



Hence,



(iv)



Since, the denominators of all the numbers are different therefore we will take LCM of the denominators.


LCM of 7, 14, 28 and 42 = 84






Clearly,


-54 < -48 < -46 < -39


Therefore,



Hence,
