No, they can be rational or irrational. The sign of a number has nothing to do with it.

Irrational.
If you have any positive irrational number, then its negative is also irrational.
A negative irrational number can be thought of as an irrational number multiplied by -1, or an irrational number with a minus sign in front of it.
If it says "negative irrational", then obviously it is irrational.
The negative of a rational number is also rational.
Not necessarily. Irrational numbers can be negative or positive.
Basically, an irrational number is one that cannot be expressed as a simple fraction.Since 4.4 is equal to 4 4/10, which reduces to 4 2/5, it is not an irrational number.

' -3pi ' is IRRATIONAL , because 'pi' is Irrational. Remember ; Rational (-3) X (Multiplied) Irrational(pi) = irrational.. Irrational numbers are those , in casual terms, decimals that recur to infinity AND there is no regular order in the decimal digits. pi = 3.141592..... So -3pi = -9.42477796..... More formally an irrational numbers is a decimal that CANNOT be converted to a RATIO/FRACTION/Quotient.
-20.3 is the ratio of -203 to 10. That's rational.
-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.
