In mathematics, a fraction is a number that represents a part of a whole. Information technology 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 up said whole. For example, in the fraction of

, the numerator is 3, and the denominator is 8. A more illustrative instance could involve a pie with 8 slices. i of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would exist the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be

every bit shown in the image to the right. Note that the denominator of a fraction cannot exist 0, as it would brand the fraction undefined. Fractions can undergo many unlike operations, some of which are mentioned below.

Add-on:

Unlike adding and subtracting integers such as 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 by the production of the denominators of each fraction. Multiplying all of the denominators ensures that the new denominator is certain to exist a multiple of each private denominator. The numerators too need to exist multiplied past the advisable factors to preserve the value of the fraction every bit a whole. This is arguably the simplest way to ensure that the fractions have a common denominator. Still, in most cases, the solutions to these equations will non appear in simplified form (the provided figurer computes the simplification automatically). Below is an example using this method.

This process can be used for any number of fractions. But multiply the numerators and denominators of each fraction in the problem by the product of the denominators of all the other fractions (not including its own corresponding denominator) in the problem.

An alternative method for finding a common denominator is to determine the least common multiple (LCM) for the denominators, then add or decrease the numerators as i would an integer. Using the least mutual multiple tin be more efficient and is more probable to consequence in a fraction in simplified class. In the example above, the denominators were 4, 6, and two. The to the lowest degree common multiple is the first shared multiple of these three numbers.

Multiples of 2: 2, four, six, viii x, 12

Multiples of 4: 4, eight, 12

Multiples of 6: 6, 12

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

Subtraction:

Fraction subtraction is essentially the same every bit fraction improver. A mutual denominator is required for the performance to occur. Refer to the addition section also as the equations below for clarification.

Multiplication:

Multiplying fractions is adequately straightforward. Different calculation and subtracting, information technology is non necessary to compute a common denominator in order to multiply fractions. Simply, 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 description.

Partitioning:

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

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

would therefore exist

. Refer to the equations below for clarification.

Simplification:

Information technology is frequently easier to work with simplified fractions. Equally such, fraction solutions are unremarkably expressed in their simplified forms.

for example, is more than cumbersome than

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

Converting between fractions and decimals:

Converting from decimals to fractions is straightforward. Information technology does, still, require the understanding that each decimal place to the right of the decimal bespeak represents a power of 10; the kickoff decimal place being ten^one, the second 10², the third 10^three, and so on. Simply determine what ability of 10 the decimal extends to, use that power of 10 as the denominator, enter each number to the right of the decimal bespeak as the numerator, and simplify. For example, looking at the number 0.1234, the number 4 is in the fourth decimal identify, which constitutes ten⁴, or 10,000. This would brand the fraction

, which simplifies to

, since the greatest common factor between the numerator and denominator is 2.

Similarly, fractions with denominators that are powers of x (or can exist converted to powers of 10) tin can exist 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 starting time decimal place represents 10^-1,

can be converted to 0.5. If the fraction were instead

, the decimal would then be 0.05, and and so on. Beyond this, converting fractions into decimals requires the operation of long segmentation.
