Since the variable may be real or complex, there is no single word or phrase to describe such a thing.
It is a term.

Irrational number
The set of rational numbers is a subset of the set of real numbers. That means that every rational number is a real number, but not every real number is rational. The square root of 2 is an example of a real number that isn't rational; that is, it can't be expressed as the quotient of two integers.
Any positive number can be written as a quotient of two positive numbers or a quotient of two negative numbers. Any real number can be written as the quotient of two real numbers.

It is called a term.

A real number is any number so yes it is always a real number * * * * * Except if the second number is 0, in which case the quotient is not defined.
Any positive number can be written as a quotient of two positive numbers or a quotient of two negative numbers. Any real number can be written as the quotient of two real numbers.
Yes but only if the denominator is 0 (so the quotient is not defined).
