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 fraction is represented of pi?

Pi is an irrational number, meaning that it cannot be written as the ratio of two integers (fractions such as 22/7 are commonly used to approximate pi; no common fraction (ratio of whole numbers) can be its exact value).

What is the number pi 3.14 in fraction form?

Pi is an irrational number, meaning that it cannot be written as the ratio of two integers (fractions such as 22/7 are commonly used to approximate pi; no common fraction (ratio of whole numbers) can be its exact value).


What is the least common denominator of two fractions?

The least common denominator is the least common multiple of the denominators of the fractions.


What are the 2 kinds of fraction?

There are common fractions, improper fractions and equivalent fractions


How do you get the common denominator for dividing fractions?

You don't need a common denominator to divide fractions.


Adding unlike fractions?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.


How do you get a common denominator for subtracting fractions?

Just multiply the two denominators of your fractions, the answer you get is a common denominator.


Is all fractions rational?

No. For example, pi/2 is a fraction which is not rational.


Which fraction is closest to 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 is a name for fractions with different common denominators?

Dissimilar fractions.


How do you find fractions from least to greatest?

you have to compare the common fractions


Do you have to find a common denomiter in dividing fractions?

No, you only need a common denominator when adding or subtracting fractions.


Do you need a common denominator for dividing fractions?

No only when adding or subtracting fractions a common denominator is needed


How do you minnous fractions?

To subtract fractions with like denominators, subtract the numerators , and write the difference over the denominator. Example : Find 45โˆ’25 . Since the denominators are the same, subtract the numerators.


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 :)


When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.


What fraction is bigger seven eighths or nine tenths?

To compare two fractions, convert them to a common denominator.To compare two fractions, convert them to a common denominator.To compare two fractions, convert them to a common denominator.To compare two fractions, convert them to a common denominator.


Why do you have to find a common denominator?

Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.


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.


How do you do equal fractions?

To compare fractions, convert both of them to a common denominator.


How do you subtract fractions with unequal denominators?

by finding the common denominator of the fractions


How can greatest common factors and least common multiples help you work with fractions?

The GCF is helpful in reducing fractions. The LCM is helpful in adding and subtracting unlike fractions.
