As much as, in these days of uncertainty, anything can be anything. As long as the constraints of a rational number are kept to, a rational number will always remain a rational number.
Yes.
Yes, but only if the rational number is 0.
Only if the rational number is 0.
A rational number which is an integer can be simplified to a form in which the denominator is 1. That is not possible for a rational number which is not an integer.
The answer depends on what the ellipsis represents. I suspect the answer is that it is irrational.
If you mean that the number continues by a number of 0s which is one more than the previous numbers of 0s followed by a 2 forever, then it is an irrational number. If you mean that the "2020020002" repeats then it is a rational number.
That terminating decimal 0.2020020002 is a rational number and is: 2020020002/10000000000 = 1010010001/5000000000 If you mean a non-terminating decimal 0.2020020002.... where each 2 is followed by one more zero than the previous 2 then it is not a rational number.
It is a rational number. It can be written as a fraction.
yes
Is 12.05 a rational number or irrational number?
1.96 is a rational number
It is a rational number, as it can be written as a fraction.
Yes, the sum is always rational.
There is no such thing as a number that is both rational and irrational. By definition, every number is either rational or irrational.

Yes, it is.
