Arrange the following rational numbers in descending 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 1, 6and 3 = 6






Clearly,


2 > -12 > -13 > -16


Therefore,



Hence,



(ii)



And,



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


LCM of 10, 15, 20 and 30 = 60






Clearly,


-18>-28>-33>-34


Therefore,



Hence,



(iii)



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


LCM of 6, 12, 18 and 24 = 72






Clearly,


-42>-52>-60>-69


Therefore,



Hence,



(iv)


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


LCM of 11, 22, 33 and 44 = 132






Clearly,


-92>-114>-117>-120


Therefore,



Hence,
