Concept wise

In standard form of rational number

• Denominator doesnβt have negative sign
• Fraction are simplified so that numerator & denominator cannot be smaller.

Β

Letβs take some examples

#### (1) Β  2/(-3)

Β Β Β Β Β  Β  2/(-3) = (-2)/3

Here 2 & 3 cannot be divided

Β

So, standard form is (-2)/3

2) π/π 2/4 Here 1 & 2 cannot be divided So, standard form is 1/2 (3) (βπ)/π 3/6 So, standard form is (β1)/2 (4) π/(βππ) 8/(β24) = (β8)/24 = (β8)/24 = (β4)/12 = (β1)/3 So, standard form is (β1)/3 (5) (βπ)/(βππ) (β6)/(β36) = 6/36 = 6/36 = 1/6 So, standard form is 1/6
