Answer 1

Well, if we had a real rational question ... .

Irrational number are all those which cannot.

supplement. A common misunderstanding, because of the alternate uses of the word 'irrational'.

In maths, the word means the number cannot be expressed as a ratio.

In everyday parlance, irrational means 'without explanation' or 'not understandable'

Answer 2

No. They are all real numbers. (as opposed to imaginary numbers)

Irrational Numbers are a very special and very limited subset of real numbers, such that they cannot be fully expressed in numeral form. Some are defined by series, square roots, or logarithms. They include pi, e, and φ.

Answer 3

No.

A number can fall into only one of those categories ... it can be either rational or irrational, but not both.

If you pick a number that is irrational, then I know immediately that it can't be rational, since no number can be both, and you've already told me which one it is.

Answer 4

No, rational number are ones that can be written as a/b where a and b are integers. Irrational numbers are those real number that are NOT rational.

Answer 5

Irrational numbers are never rational numbers

Answer 6

No. It's one or the other. No rational number is irrational.

Answer 7

No, they are disjoint sets: no rational is irrational and no irrational is rational.
