Every irrational number can be expressed as a quotient of integers?
WRONG!!!!! Irrational numbers CANNOT be expressed as a quotient(fraction). Casually, irrational numbers are those were the decimals go to infinity AND there is no regular order in the decimal digits. e.g. pi = 3.1415192.... is Irrational 3.3333.... is rational.
Is 3.12 irrational?
NO!!!! Irrational numbers are thouse were the decimals go to inifinity AND there is no regular order in the decimal digits. 'pi' of circular fame is probebly the most well known irrational number at ;- 3.141592..... NB Any terminating decimal e.g. 3.12 is NOT irrational.
Is 18 an irrational number?
NO!! Irrational Numbers are those where the decimal digits go to infinity AND there is no regular order in the decimal digits. pi = 3.141592.... is the most well known irrational number. as are the 'Square roots' od prime numbers;-# sqrt(2) = 1.414213.... sqrt(3) = 1.73205... sqrt(5) = 2.23606... However, such as numbers as 3.3333..... is NOT irrational, because the decimals are in regular order. Similarly 2.373737.... or 5 .678678678.... Are NOT irrational because the decimals are in a regular order. NB '....''' at the end of a decimal is the mathematical indication of recurring to infinity.

Just like every brushstroke adds beauty to a painting, every number has its place in the vast world of mathematics.
