Best Answer

Rational.

All counting numbers (1, 2, 3 etc.) are rational. In fact many fractions/decimals are rational too. Rational just means that we know when the numbers stop.

A good example of an irrational number is Pi, which equals 3.14159265358979.... and it just keeps going. No one knows the exact number of pi because as far as anyone can tell, the numbers keep going forever without any proper repeating pattern.
