Most numbers are real numbers, but they are called that to distinguish them from imaginary ones. The best example of an imaginery number is the square root of minus 1. This is not a possibility.

Real #'s include both rational #'s (42 or -36/234), and irrational #'s (Pi or the square root of 6); or they can be given by infinite decimal representation (34.634526347457452.....); real #'s can be thought of as points on an infinitely long # line.
examples: 1, 2, 0, -5, sqrt(2), pi etc. real numbers means numbers on the real plane. the opposite of real numbers are imaginary numbers which takes the format of ai, in which the i is the imaginary unit they do not exist on the real plane, but only on the imaginary plane. they can be found by square-rooting a negative number, e.g. sqrt(-4)=2i usually imaginary numbers are used with real numbers, with the format a+bi, and this is called complex numbers.
there are a lot of examples of whole numbers 1,2,3,4,5,6,7,8,9. . .

False. Irrational numbers are real numbers.
