Yes, but only if the rational number is 0.
It will be irrational.
If you multiply a rational and an irrational number, the result will be irrational.
Irrational. If you multiply a rational number by an irrational number, you will always get an irrational number (except if the rational number happens to be zero).
Yes.
The product of an irrational number and a rational number, both nonzero, is always irrational
-Pi is irrational, because it does not terminate or repeat. Whenever you multiply an irrational number by a rational number (-1), the result is an irrational number.
Yes. Any time you multiply a rational number by an irrational number, you get an irrational number - unless the rational number is zero.

No.
no
Sqrt(2) is irrational. Multiply by sqrt(4.5). Result is 3 which is rational.
No irrational number can turn into a rational number by itself: you have to do something to it. If you multiply any irrational number by 0, the answer is 0, which is rational. So, given the correct procedure, every irrational number can be turned into a rational number.
