In mathematics, a fraction is a number that represents a function of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make upwards said whole. For case, in the fraction of

, the numerator is 3, and the denominator is viii. A more illustrative example could involve a pie with 8 slices. one of those 8 slices would institute the numerator of a fraction, while the full of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be

as shown in the image to the right. Note that the denominator of a fraction cannot be 0, equally information technology would brand the fraction undefined. Fractions can undergo many dissimilar operations, some of which are mentioned below.

Addition:

Different adding and subtracting integers such every bit 2 and 8, fractions require a common denominator to undergo these operations. One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved past the product of the denominators of each fraction. Multiplying all of the denominators ensures that the new denominator is sure to be a multiple of each individual denominator. The numerators likewise need to be multiplied by the advisable factors to preserve the value of the fraction as a whole. This is arguably the simplest way to ensure that the fractions have a common denominator. However, in most cases, the solutions to these equations will not appear in simplified class (the provided estimator computes the simplification automatically). Below is an instance using this method.

This procedure can exist used for any number of fractions. Simply multiply the numerators and denominators of each fraction in the problem by the product of the denominators of all the other fractions (non including its own respective denominator) in the problem.

An alternative method for finding a mutual denominator is to determine the least common multiple (LCM) for the denominators, and then add together or subtract the numerators as one would an integer. Using the to the lowest degree common multiple tin exist more efficient and is more likely to consequence in a fraction in simplified class. In the example above, the denominators were four, half-dozen, and 2. The least common multiple is the first shared multiple of these 3 numbers.

Multiples of 2: 2, 4, half dozen, 8 10, 12

Multiples of 4: 4, eight, 12

Multiples of half dozen: 6, 12

The get-go multiple they all share is 12, and so this is the least common multiple. To complete an add-on (or subtraction) problem, multiply the numerators and denominators of each fraction in the problem by whatever value will make the denominators 12, then add the numerators.

Subtraction:

Fraction subtraction is essentially the aforementioned as fraction addition. A common denominator is required for the operation to occur. Refer to the add-on section equally well every bit the equations below for description.

Multiplication:

Multiplying fractions is fairly straightforward. Unlike calculation and subtracting, it is not necessary to compute a mutual denominator in order to multiply fractions. Just, the numerators and denominators of each fraction are multiplied, and the result forms a new numerator and denominator. If possible, the solution should be simplified. Refer to the equations below for clarification.

Segmentation:

The procedure for dividing fractions is similar to that for multiplying fractions. In order to divide fractions, the fraction in the numerator is multiplied by the reciprocal of the fraction in the denominator. The reciprocal of a number a is simply

. When a is a fraction, this essentially involves exchanging the position of the numerator and the denominator. The reciprocal of the fraction

would therefore be

. Refer to the equations below for clarification.

Simplification:

It is oft easier to work with simplified fractions. As such, fraction solutions are ordinarily expressed in their simplified forms.

for case, is more cumbersome than

. The calculator provided returns fraction inputs in both improper fraction form as well as mixed number form. In both cases, fractions are presented in their lowest forms by dividing both numerator and denominator by their greatest common factor.

Converting betwixt fractions and decimals:

Converting from decimals to fractions is straightforward. Information technology does, however, require the understanding that each decimal place to the right of the decimal bespeak represents a ability of 10; the kickoff decimal place being ten¹, the 2d 10ⁱⁱ, the third x³, and so on. Merely determine what power of ten the decimal extends to, employ that power of ten every bit the denominator, enter each number to the right of the decimal point as the numerator, and simplify. For case, looking at the number 0.1234, the number 4 is in the fourth decimal identify, which constitutes 10⁴, or 10,000. This would make the fraction

, which simplifies to

, since the greatest common factor betwixt the numerator and denominator is ii.

Similarly, fractions with denominators that are powers of 10 (or can be converted to powers of x) can be translated to decimal form using the same principles. Take the fraction

for example. To convert this fraction into a decimal, first convert it into the fraction of

. Knowing that the first decimal place represents 10^-1,

can be converted to 0.5. If the fraction were instead

, the decimal would then exist 0.05, and so on. Beyond this, converting fractions into decimals requires the performance of long sectionalisation.
