Best Answer

That is not what mathematicians mean by an irrational number, which is a number with an infinitely long decimal expansion. You will note that since division is the inverse of multiplication, dividing by small numbers has the same effect as multiplying by large numbers, and so dividing by zero, which is an infinitely small number, is equivalent to multiplying by infinity. The result in most cases is deemed to have no mathematical meaning.

At least one of the factors has to be irrational.* An irrational number times ANY number (except zero) is irrational. * The product of two irrational numbers can be either rational or 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).

It is usually irrational but it can be rational if the ration number in the pair is zero. So the correct answer is "either".

Rational number can be divided into more that the number 2. Irrational number are numbers that can only be divided evenly with the number 2.

Any rational number (by definition).

An irrational number. Nothing may be rationally divided by zero.

Irrational.

Yes. Any irrational number can be divided by itself to produce 1, which is a rational number.

If you multiply an irrational number by ANY non-zero rational number, the result will be irrational.

Such a product is always irrational - unless the rational number happens to be zero.

Unless the rational number is zero, the answer is irrational.

Yes, an irrational number divided by an irrational number will usually be an irrational number, but not always. For example, pi / (3pi) is 1/3, which is a rational number, but pi/e is an irrational number.

Not if the rational number is zero. In all other cases, the product is irrational.
