.63 Repeating as a Decimal
In mathematics, repeating decimals are a type of decimal representation that never ends and never repeats in a predictable pattern. One of the most common repeating decimals is .63.
What is .63 Repeating?
.63 repeating, also written as 0.636363..., is a decimal representation of a rational number. A rational number is a number that can be expressed as the ratio of two integers, such as 1/2 or 3/4. In the case of .63 repeating, it is equal to 63/99.
How to Write .63 Repeating as a Fraction
To write .63 repeating as a fraction, we can use the following formula:
.63 = 63/99
This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 9.
.63 = 63/99 = 7/11
Properties of .63 Repeating
.63 repeating has several interesting properties:
- Recurring pattern: The decimal representation of .63 repeating has a recurring pattern of 63, which repeats indefinitely.
- Rational number: .63 repeating is a rational number, which means it can be expressed as the ratio of two integers.
- Irrational square root: The square root of .63 repeating is an irrational number, which means it cannot be expressed as a finite decimal or fraction.
