    2.22, when multiplied by 0.5, results in 1.11.

    1.11, in turn, can be written as 111/100, which is a rational number.

    D is the correct answer choice.

    It's D, because it's a rational number and "rational * rational = rational", while "rational * irrational = irrational" and the other three numbers are all irrational ones.
