<PRE><B>Question 154905</B>
negative .75 would be classified as a rational number because it can be written
as -75/100
----------------------

I am not for sure if it is classified as a real rational number and a integer or just a real and irrational number. 
-----------------------------
natural numbers: all positive whole numbers
--------------------------------------------------
integers : all positive and negative whole numbers and zero
--------------------------------------------------
rational numbers: any number that can be written as the ratio of two integers
or any number whose decimal form is a continuing pattern
--------------------------------------------------
irrational numbers any number whose decimal form does not have a continuing
pattern
--------------------------------------------------
real numbers: any number that is rational or irrational
--------------------------------------------------
Comment: You will find additional information on these number types if
