Another rational expression.
Yes.
Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.
The expression written in the question is the rational expression.
Yes, but the converse is not true.
Another rational expression.
Yes.
If you divide a rational expression by another rational expression, you will again get a rational expression.
The question is meaningless. 50,550,555 is a rational number.
a rational express ion undefined when the denominator is 0 because we cannot dvide by 0. For example, 9/x is undefine when x is 0 because we would be dividing by 0. Similarly 2/(7-x) is undefined for x=7 because we once again have a zero in the denominator. To find where a rational expression is undefined, set the denominator equal to 0 so if we have p/q where q is any number or expression, set and solve q=0 From, Doctor Huge Dick

"Have a nice day" is a meaningless modern American English expression devised by the retail industry and there is definitely nothing equivalent to it in any rational historic language.
I can see no rational expression below.
The expression is not factorable with rational numbers.
another rational expression.
A rational expression is not defined whenever the denominator of the expression equals zero. These will be the roots or zeros of the denominator.
