A rational number can be expressed as a simple fraction, an irrational number cannot.
More formally:
A rational number is any real number that can be expressed as a ratio of two integers (positive or negative whole numbers).
(The denominator in the ratio cannot be zero.)
An irrational number cannot be expressed in that way.
The terms "rational" and "irrational" refer to the idea of "ratio".
If it can't be expressed as a fraction then it is an irrational number
Irrational.
The product of a rational and irrational number can be rational if the rational is 0. Otherwise it is always irrational.
No.A rational times an irrational is never rational. It is always irrational.
It will be irrational.
rational * irrational = irrational.
It is a rational number.
It is rational. An irrational number is a number that you cannot define by a fraction or a decimal. Since you wrote it as a decimal, it is rational.

The same as you would a rational number. Its distance from zero will represent the number, whether it is rational or irrational.
No.
If its decimal representation is either terminating or a repeating number then it is rational. Otherwise it is irrational.
10.01 is a rational number
If it can't be expressed as a fraction then it is an irrational number
Quite simply, a number that is not a rational number. And a rational number is one that can be written as a fraction, with integer numerator and denominator.
Rational
It is rational. An irrational number is a number that you cannot define by a fraction or a decimal. Since you wrote it as a decimal, it is rational. The fact that it is negative does not matter.
