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,
