For ten points, name this type of number whose decimal expansion either terminates or repeats and which can be written as a fraction.
A number is algebraic if it is the root of a polynomial with these numbers as coefficients. You can list these numbers, unlike a complement set that includes pi and the square root of (*) two. 0.2 and 0.3, with the 3 repeating, are both examples of this type of number.
