Express each of the following rational numbers in its standard form:

A.

B.

C.

D.

A. Considering the rational number =

-12 = 2 × 2 × 3 × -1

72 = 2 × 2 × 2 × 3 × 3

H.C.F. = 12

To convert into it’s standard form,

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

⇒

⇒

B. Considering the rational number =

14 = 2 × 7

-49 = 7 × 7 × -1

H.C.F. = 7

To convert into it’s standard form,

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

⇒

⇒

C. Considering the rational number =

-15 = 3 × 5 × -1

35 = 5 × 7

H.C.F. = 5

To convert into it’s standard form,

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

⇒

⇒

D. Considering the rational number =

299 = 13 × 23

161 = 7 × 23

H.C.F. = 23

To convert into standard form,

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