No, the set of mixed numbers is a subset of the set of rational numbers. For example the mixed number 1 Â¼ is the same as the improper fraction 5/4 [a rational number]. Note that it is a subset, because integers are also rational numbers, but a mixed number will not be an integer. Also, any fraction between 0 and 1 will not be a mixed number.

This number is rational - all fractions, including decimal fractions and mixed numbers are rational.
