There are an infinite number of subsets: All rationals other than 1 All rationals other than 2, etc All rationals other than 1.1 All rationals other than 2.1, etc, etc. All integers
yes
All rationals are real, so everything that is true of the reals is also true of the rationals, and vice versa.

No.
YES
Yes it is. Repeating decimals are all repeating rationals.
multiply the decimal by 100
Yes, it is a repeating decimal. Terminating and repeating decimals are rationals. Rational numbers can also be expressed as a fraction. 0.313131 is a repeating decimal.

yes
We use Q for Rationals... which is repreentative of Quocentia (Quotient), since rationals are RATIOs or fractions.
It could be the set denoted by Q- (the non-positive rationals) or Q+ (the non-negative rationals).
what are irrational and radicals and rationals
All rationals are real, so everything that is true of the reals is also true of the rationals, and vice versa.
The number of rationals is Aleph-null.
