A rational number can be expressed as a simple fraction, an irrational number cannot.
More formally:
A rational number is any real number that can be expressed as a ratio of two integers (positive or negative whole numbers).
(The denominator in the ratio cannot be zero.)
An irrational number cannot be expressed in that way.
The terms "rational" and "irrational" refer to the idea of "ratio".
