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.
