Well, sweetheart, a rational number is any number that can be expressed as a fraction, and 0.18 is no exception. You can write 0.18 as 18/100, which can be simplified to 9/50. So, yeah, 0.18 is rational, just like your decision to ask me this question.
Any terminating or non-terminating decimal digit is rational.
The easiest way to look at this is, writing the number in the fractional from.
0.18 can be written as 18/100.
Now, by the definition of a rational from, 18/100 is of the standard "p/q" from where q is not equal to 0 (q=100 here).
Thus, it is a rational number.
yes
Yes.
It must be a generalised rational number. Otherwise, if you select a rational number to multiply, then you will only prove it for that number.
yes
Yes. Any rational number divided by another rational number is also rational.
It is a rational number. It can be written as a fraction.
yes

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.
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, it is.
It is a rational number.
