Question 342574: If a number is rational, then would it also be an integer, whole, real, and natural number? Would 3.2 be a rational number? I need a VERY simple definition of a rational and irrational number.

You can put this solution on YOUR website! a RATIOnal number is any number which can be expressed as the RATIO of two whole numbers
___ irrational numbers are everything else
3.2 = 16/5
the imperfect roots are irrational ___ sqrt(2) , cuberoot(7) , etc.
rational numbers are real , but not all real numbers are rational ___ pi, e and the above roots are examples
integer, whole, and natural numbers are rational ___ but not necessarily vice-versa
