Rational And Irrational Numbers
The most irrational number turns out to be a number already well known in geometry. It is the number g = ( + 1)/2 = 1.618033. which is the length of the diagonal in a regular pentagon of side length 1. This number, known as the "golden mean," has played a large role in mathematical aesthetics.

Irrational numbers are numbers that cannot be expressed as the ratio of two whole numbers. This is opposed to rational numbers, like 2, 7, one-fifth and -13/9, which can be, and are, expressed as.
Irrational Number Definition What It Is and How To Use It
Wrath, Actually, Sal was saying that there are an infinite number of irrational numbers. And there is at least one irrational number between any two rational numbers. So there are lots (an infinite number) of both. And saying one thing that is infinite is more than another infinite thing is questionable because you can't add to infinite.
What are Irrational Numbers? List, Properties, Arithmetic Operations
An irrational number is a real number that cannot be written as a ratio of two integers. In other words, it can't be written as a fraction where the numerator and denominator are both integers. Irrational numbers often show up as non-terminating, non-repeating decimals. Learn more with our Intro to rational & irrational numbers video.

These measures reveal that the most irrational number, i.e. the one for which rational approximations perform the worst, is 1 plus the square root of 5 all divided by two - a figure roughly equal to 1.618. This number is already well known. It's called the "Golden Ratio".

The number ฮฆ is known as the golden ratio. Two positive numbers x and y, with x > y, are said to be in the golden ratio if the ratio between the sum of those numbers and the larger one is the same as the ratio between the larger one and the smaller; that is, x + y x = x y. Solution of (2.2.1) yields x / y = ฮฆ.
