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,
