Question

What is an irrational number?

Answer 1

Examples: π = 3.1415926..... and √2

Explanation:

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.

Answer 2

An irrational number is a number that cant be written as a ration of two integers. (Can't be written as a ratio or fraction.)

Explanation:

Example: π (Pi) is a famous irrational number.

Example: 9.5 can be written as a simple fraction like this:

9.5 = 192

So it is a rational number (and so is not irrational)
