Answer:

It's both real and rational.

Explanation:

The collections from wider to narrower:
(1) All numbers (including complex numbers, combinations with #i=sqrt(-1)#)
(2) Real numbers (excluding #i=sqrt(-1)#)
(3) Rational numbers can be written as the quotient, or fraction, or ratio, of two whole numbers, irrational numbers (like #pi# or #sqrt2#) cannot.
(4) Whole=integer numbers are what they say they are
(5) Natural numbers are positive whole numbers
