A decimal is a rational number if:* It terminates - i.e., it has a finite number of decimal digits.
* It doesn't terminate, but it repeats the same pattern over and over - possibly after a finite number of digits that are not included in the pattern. For example, 0.145145145145..., or 3.125252525...
