Reduce each of the following rational numbers in its lowest form:

(i)

(ii)

(i) Considering the rational number =

-60 = 2 × 2 × 3 × 5 × -1

72 = 2 × 2 × 2 × 3 × 3

H.C.F. = 12

To convert into it’s lowest form,

Divide the numerator and denominator by H.C.F.

⇒

⇒

(ii) considering the rational number =

91 = 7 × 13

-364 = 2 × 2 × 7 × 13 × -1

H.C.F. = 91

To convert into it’s lowest form,

Divide the numerator and denominator by H.C.F.
