suppose u have 2 lines,
the first line of length (a).
the second of length (b).
if it is possible to make the two lines the same length using any number of a versus any number of b then they are rational.
this is in the form of
x = a/b
if it is irrational then u can never make line a = line b no matter how many times u multiply them.
this is in the form
x = a/b+k

Rational nos can be xpressed in p/q
form i.e. fraction
and they r terminating or recurring decimals,
Irratinal nos r those which
cannot be xpressed in p/q form
or r non-recurring, non terminating decimals
