-- Any decimal that ends is a rational number.
-- Any decimal that never ends may or may not be a rational number.
-- The decimal representation of an irrational number never ends.
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. Fractions do not include irrational numbers. And although there are an infinite number of both rationals and irrationals, there are far more irrational numbers than rationals.
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.

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