Question

is -2 1/3 rational or irrational?

Answer 1

For further reference, this might help:
A number is rational if we can write it as a fraction where the top number of the fraction and bottom number are both whole numbers. Alternatively, an irrational number is any number that is not rational. It is a number that cannot be written as a ratio of two integers (or cannot be expressed as a fraction).
