34.5 is RATIONAL. Irrational numbers are those were the decimals go to infinity AND there is no regular order in the decimal numbers. Definitively an Irrational Number CAnnot BE CONVERTED TO A quotient/ratio/frACTION pi = 3.141592.... is the most well known irrational number. So 34.5 is rational 34.55555..... is rational (gOES TO INFINITY ; numbers in regukar order). 34.565656.... is Rational (Goes to infinity ; numbers in regulkar order). et seq., The dots after the number mean it continues to infinity . However, 34.25865414..... is Irrational . Because there is no regular order in the decimal digits.
it is a rational number but 4.121314..... is an irrational no
