Answer: Irrational

We cannot write sqrt (12) as a fraction of two whole numbers

Note how sqrt (12) = 3.464 and the decimal portion goes on forever without any known pattern (and it doesnt repeat either).

Compare this to something like sqrt (16) = 4 which can be written as a fraction 4/1, so sqrt (16) is rational
