Definitions for **"Irrational number"**

A number that cannot be expressed either as a quotient of two integers or as a repeating or terminating decimal, for example, are irrational numbers.

A number that cannot be expressed as a repeating or terminating decimal Example: pi and the square root of 5

A number that is not rational.

a real number that cannot be expressed as a rational number

a cut separating all rational numbers into two classes, an upper and lower class ( set )

a non-repeating, non-terminating decimal

a number that cannot be expressed as a fraction for any integers and

a number that cannot be expressed in the form (a / b) where a and b are integers

a number that cannot be written as a simple fraction - it's decimal goes on forever without repeating

a number that you cannot conceptualise

a number which cannot be expressed exactly in any algebraic or arithmetical form

a number with a decimal that neither terminates or repeats

a real number that cannot be reduced to any ratio between an integer and a natural number

A number that cannot be written as a simple fraction. It is an infinite and non-repeating decimal.

number that cannot be expressed as (a / b) where b is not equal to zero

A number that cannot be expressed as a repeating or terminating decimal. Example: 21/2 = 1.414213562... .

a real number whose decimal representation neither repeats nor terminates; may also be defined as a real number which cannot be expressed in fraction form as a/b where a and b are Integers (e.g., both Ö and are irrational)

A number that cannot be expressed as the ratio of two integers. The first irrational number to be discovered was the square root of 2. "Most" real numbers are irrational.

a number that cannot be written in fraction form. For example, the number cannot be written in fraction form.

a real number that cannot be expressed as a ratio of two numbers (e.g., þ).

An irrational number is a number that cannot be written as a fraction (like a/b, where a and b are whole numbers and b is â‰ 0). For example, the square root of 2 is an irrational number.

A number that cannot be expressed as a quotient of two integers, e.g., âˆš2. It can be shown that a number is irrational if and only if it cannot be written as a repeating or terminating decimal.

s - nonrational numbers

A number that cannot be represented as an exact ratio of two integers. For example, the square root of 2 or p .

A number which cannot be represented in fractional form,such as PI (3.14159..).

A real number that cannot be represented as a fraction.

A real number that cannot be represented as an exact ratio of two integers. The decimal form of the number never terminates and never repeats. Examples: The square roots of 2 or Pi.

In mathematics, an irrational number is any real number that is not a rational number, i.e., it is a number not of the form n/m, where n and m are integers. Almost all real numbers are irrational, in a sense which is defined more precisely below.

A number in which the decimal portion never ends and doesn't repeat (Dec. 14, p. 8)
