pi is an irrational number and so has an infinitely long, non-recurring decimal representation. So given any fraction, it is possible to get a nearer fraction by adding another decimal digit.For example, consider the sequence:
3 = 3/1
3.1 = 31/10
3.14 = 314/100
3.142 = 3142/1000
3.1416 = 31416/10000
Each fraction is closer than the one above but this sequence never ends.

How do you write pi as an improper fraction?
Pi written as an improper fraction is 22/722 over 7
Are all fractions rational numbers?
No. pi/2 is a fraction but, since pi is irrational, so it pi/2.
Is pi an irrational or a rational number?
Pi is an irrational number. A rational number is one that can be expressed as a fraction (or ratio), e.g. 1/3. There are fractions that are near Pi, for example: 22/7 = 3.142857 (PI = 3.14159265...) A closer fraction is: 355/113 = 3.14159292 However whatever fraction you have, you will never get exactly PI. Hence it is irrational See the links for proofs that pi is irrational.
How many digits are in the number Pi?
As many as you like; pi is an irrational number. That means that there are no two whole numbers that you can make into a fraction exactly equal to pi. It also means that if you start to calculate pi as a decimal it never ends and never recurrs. It just goes on forever. A few years ago two Japanese people calculated pi to eight million places of decimals, which they then published in a book. It just never ends. * * * * * Update: in October 2011, pi to 10 trillion (and 50) digits was published. See link.
Is pi a repeating decimal?
Basically No, The number pi has a decimal fraction that goes on forever and never falls into a repeating pattern. That is characteristic of irrational numbers like pi.
What fraction is the closest to the actual value of pi?
One can define an infinite number of fractions to successively approximate pi, and get closer and closer to pi's value. There is no closest fraction to pi. No matter how close the fraction is to pi you can always find one that is closer.
What fraction is closest to 5?
One can define an infinite number of fractions to successively approximate pi, and get closer and closer to pi's value. There is no closest fraction to pi. No matter how close the fraction is to pi you can always find one that is closer
What is the fraction close to pi?
22 over 7 is the fractiron closest to pi
What is the closest fraction to Pi?
22 over 7
What is the closest approximate fraction form of the number Pi?
It is: 22/7
What numbers can you divide to get the closest to pi?
The fraction 22/7 is close to PI for four significant digits.
What is the formula for pi?
Pi is a number. You get pi when you divide the circumference of a circle by it's radius. 22/7=3.14 is the closest fraction.
Why is pi equal to 227?
22 divided by 7 is 3.14, making 22/7 the closest fraction to the value of pi.
Can pi be written as a fraction?
22/7 I think is the closest fraction you will get. By definition it is irrational, and cannot be written as fraction of integer numbers. There are a few fractions that are close approximates though. Pi cannot be technically written as a fraction. However, a fraction that is a close approximation of pi is 22/7.
Which fraction is closest to the acual Pi 337 120 or 22 7 or 355 113?
337/120
Can the exact value of PI be calculated?
"Not as a decimal or fraction as there are an infinite number of digits." This is a common and useful answer. The *correct* answer is that PI is firstly an irrational number that cannot be calculated from any ratio (fraction). Secondly, PI is a transcendental number that, by the definition of "transcendental", cannot be exactly calculated. The nest you can do is to apply an infinite convergent series that becomes more and more accurate with more and more decimal places.
What are some fractions that are almost equivalent to pi?
22/7 or 3 1/7 is the closest known fraction
