Select "rational" or "irrational" to classify each number. rational irrational 23 π 400−−−√ 36√2

Rational: A number is rational if it can be written in the form of p/q, where q≠0, and it is terminating if q is of the form where m and n are whole numbers or non terminating repeating.

Irrational number: A number which can't be written in the form of p/q, i.e the number after decimal does not terminates.It is non terminating repeating.

1. 2/3 =0.66666...(non terminating repeating)   = Rational

2. π  =3.14159 26535 ........(non terminating non repeating)=Irrational

3.√400 =20 (terminates)=Rational

4. 36√2 = as √2=1.414.....(non terminating non repeating)=Rational×Irrational=Irrational
