Yes.
A rational number can be expressed as a ratio of two integers, p/q where q > 0. An irrational number cannot be expressed in such a way.
No, it is always irrational.
Next to any rational number is an irrational number, but next to an irrational number can be either a rational number or an irrational number, but it is infinitely more likely to be an irrational number (as between any two rational numbers are an infinity of irrational numbers).

-- There's an infinite number of rational numbers. -- There's an infinite number of irrational numbers. -- There are more irrational numbers than rational numbers. -- The difference between the number of irrational numbers and the number of rational numbers is infinite.
Yes.
There is no number which can be rational and irrational so there is no point in asking "how".
A rational number can be expressed as a ratio of two integers, p/q where q > 0. An irrational number cannot be expressed in such a way.
No, it is always irrational.
Yes. 2+sqrt(3) and 5+sqrt(3). Their difference is 3, which is rational.
Next to any rational number is an irrational number, but next to an irrational number can be either a rational number or an irrational number, but it is infinitely more likely to be an irrational number (as between any two rational numbers are an infinity of irrational numbers).
The sum or the difference between two irrational numbers could either be rational or irrational, however, it should be a real number.
A rational number is a real number that can be expressed as a ratio of two integers; an irrational number cannot be so expressed.
Yes. Google Cauchy's proof.
In between any two rational numbers there is an irrational number. In between any two irrational numbers there is a rational number.
