Is 16 rational or irrational?
Rational!!!! Consider ALL numbers to be rational , except those decimals that gor to infinity AND there is no regular order in the decimal digits. Rational ; 2.33333..... Because the decimals are in a regular order. Irrational ; 3.141592.... Because the decimals are in an irregular order. The mathematical definition of irrational numbers that they cannot be converted to a quotient(fraction). NB The three or more stops after the last decimal is the mathemtical indication that it recurs to inifinity. If no stops are shown, then it is deemed to be a terminal decimal. e.g. 2.333 is a terminal decimal 2.33333..... is a decimal recurring to inifity. NNB pi = 3.141592... is the most well known irrational number. However, the 'Square Roots' of prime numbers are also irrational e.g. sqrt(2) = 1.414213562.... sqrt(19) = 4.358898944....
