What are some examples of a fraction but not a rational number?
A rational number is a fraction with an integer in the numerator, and a non-zero integer in the denominator. If you consider pi/2, pi/3, pi/4 (common 'fractions' of pi used in trigonometry) to be 'fractions', then these are not rational numbers.
What are some facts about Irrational numbers'?
Irrational numbers are numbers that can't be expressed as fractions and are never ending decimals that can't be expressed as fractions as for example the value of pi as in a circle.
What is the equivalent fraction for pi?
pi is an irrational number and so there is no equivalent fraction.
Is all fractions rational?
No. For example, pi/2 is a fraction which is not rational.
What is Almost equal to 3.1415?
Pi

Are all fractions rational numbers?
No. pi/2 is a fraction but, since pi is irrational, so it pi/2.
What do pi have in common with fractions?
They are both about math, i guess
What are some facts about Irrational numbers'?
Irrational numbers are numbers that can't be expressed as fractions and are never ending decimals that can't be expressed as fractions as for example the value of pi as in a circle.
What is the equivalent fraction of 5 over 10?
There are an infinite number of fractions that are equivalent to 5/10. Here are a few of them: 1/2 2/4 3/6 4/8 6/12 7/14 8/16 9/18 10/20 pi/(2 pi)
What is the equivalent fraction for pi?
pi is an irrational number and so there is no equivalent fraction.
How do you calculate circumference of a circle using fractions as pi?
Pi is 22/7. Therefore, the equation for finding the circumference of a circle using fractions is: 22/7 mutiplied by the diameter of the circle :)
What is the Equivalent decimal to Pi?
pi (π) = 3.14159265
Is all fractions rational?
No. For example, pi/2 is a fraction which is not rational.
What is Pi as an estimated fraction?
There are an infinite number of fractions that could be used as estimates for (pi).Some are closer to the accurate value, some are not so close.Personally, I like 22/7 . It's easy to remember, easy to use, and only 0.04% too big .
What is Almost equal to 3.1415?
Pi
What fraction is the equivalent of pi?
pi is irrational so there can be no fraction that is equivalent. 22/7 is often used as a simple approximation.
