# How Can We Guess That Whether The Number Is Rational Or Irrational ?

Rational numbers include:

All integers, ....-3,-2,-1,0,1,2,3.....

All fractions like 2/3, 3/4, 5/6, 1/2 etc.

All normal decimals like 1.3, 2.56, 0.4 etc.

√2, √5 are NOT rational numbers since we cannot express in the above forms.

π is NOT rational number because it is a never ending decimal.

By definition, a rational number is a number that can be written in the form p/q where p and q are integers and q is not equal to zero.
