2)Name the sets of numbers to which 457 belongs.

(answer)natural,whole,integers,rational,reals

My book says that every REAL number has to be rational or irrational.

Blueridge said that my answer was correct except to exclude rational from my list. From what my book says I HAVE to include rational or irrational right? so which one is it?
