Real numbers include?

Real numbers include real numbers. XD.

Ok, ok, real numbers include all rational and irrational numbers. A rational number is any number that can be written as the quotient of two integers. (An Integer is a whole number). An Irrational number well you probably guessed it, is any number that can't be written as a fraction. For example Pi goes on forever and ever. Pi doesn't have any repeating numbers and can't be a fraction. Therefor it must be irrational. Real numbers can be used to tell distance, speed, etc. Real numbers are mostly put on the number line and we all know that goes on forever and ever just like pi.
