Yes and an irrational number can't be expressed as a fraction
Any irrational number can be approximated by decimals. You can never write it exactly, since there are an infinite number of decimals, and these don't repeat.
No. Anything that has a finite number of decimals (or repeating decimals) is a rational number.
Infinitely many. pi is not just an irrational number but a transcendental number. All irrational numbers have infinite decimals that do not go into a recurring pattern.
Yes. Rational numbers are numbers or decimals that repeat or terminate. Irrational numbers do not. For example π is an irrational number.
An irrational number can be represented by a non-terminating, non-repeating decimal.

No. Repeating decimals are rational.

Irrational numbers are non-repeating, non-terminating decimals. If your number repeats, it's rational. If it doesn't, it's irrational.
An irrational number can be represented by a non-terminating, non-repeating decimal.
Repeating decimals are rational numbers if there is a pattern, like 0.22222222. If it is not a pattern, like 0.568964329, it is an irrational number.
Any number with a finite number of decimals is rational.
Any number with a finite amount of decimals is rational.
The square of a rational number can be either rational or irrational. However, the square of an irrational number is always irrational.
3501225 is a rational number. (It is even a natural number.) (Decimal representation of an irrational number has not terminating or repeating decimals.)
