Question

(iii)
p/q
is a non-zero rational number in standard form. It is necessary that rational number q/p
.
will also be in standard form.
​

Answer 1

q/p is also possible in to represent standard form of rational number when P not equal to zero.

Answer 2

quest

p/q

is a non-zero rational number in standard form. It is necessary that rational number q/pwill also be in standard form.

solution:

first condition

if p/q is in standard form , the. Highest common factor Of p and q will be 1 .

hence p/q also have p and q having HCF 1 .

second condition :

if in p/q , p can be negative . in such case p/q will have a negative denominator . hence it will not be in standard form .

for example --

$\frac{ - 3}{5} \mathsf{is \: in \: standard \: form \: while \frac{5}{ - 3} is \: not \: in \: standard \: form}$
