Not always. For example sqrt(2) and 1/sqrt(2) are both irrational, but their product is the rational number 1.
Yes. A number can be either rational or irrational, but never both; otherwise there would be an inherent contradiction.
No number can be both rational and irrational. And, at the level that you must be for you to need to ask that question, a number must be either rational or irrational (ie not neither). 0.555555 is rational.
There is no such thing as a number that is both rational and irrational. By definition, every number is either rational or irrational.

No natural number is irrational.
No. No natural number can be irrational.
The number 12 is a natural number, a whole number, an integer, and a rational number. A natural number is a positive integer starting from 1, which includes 12. Whole numbers include all natural numbers along with zero, so 12 is also a whole number. Integers include all whole numbers along with their negatives, making 12 an integer. Lastly, a rational number is any number that can be expressed as a fraction, and 12 can be written as 12/1, making it a rational number.
No.
No. 328143 is not an irrational number. It is a real, rational, whole, and natural number.
It is a natural number and an integer.
It will be irrational.
A prime number is a natural number that has no natural number as a factor other than itself or 1. An irrational number is not a natural number, so an irrational number can't be prime.
No
No, no number can be both rational and irrational.
Yes normally but if both irrational number are the same then the quotient will be 1
20 is both rational and natural. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
