**irrational number**is real

**number**that cannot be expressed as a ratio of two integers. The

**number**"pi" or π (3.14159) is a common

**example**of an

**irrational number**since it has an infinite

**number**of digits after the decimal point. Many square roots are also

**irrational**since they cannot be reduced to fractions.

Subsequently, one may also ask, what is an irrational number give examples?

It is a **number** that cannot be written as a ratio of two integers (or cannot be expressed as a fraction). For **example**, the square root of 2 is an **irrational number** because it cannot be written as a ratio of two integers.

One may also ask, what is an irrational number for kids? a nonrepeating or nonterminating decimal but not as a fraction, the decimal goes on forever without repeating. EXAMPLES: Phi, pi and the square root of any prime **number** are **irrational numbers**.

Similarly, what is a irrational number simple definition?

A **number** that cannot be expressed as a ratio between two integers and is not an imaginary **number**. If written in decimal notation, an **irrational number** would have an infinite **number** of digits to the right of the decimal point, without repetition. Pi and the square root of 2 (√2) are **irrational numbers**.

Is 5 an irrational number?

Rational **Numbers 5**/1, 1/2, 1.75, -97/3 **Irrational**, then, just means all the **numbers** that aren't rational. Every integer is a rational **number**, since each integer n can be written in the form n/1. For example **5** = **5**/1 and thus **5** is a rational **number**.
