In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator và a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that trang điểm said whole. For example, in the fraction of

3
8
, the numerator is 3, và the denominator is 8. A more illustrative sầu example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were khổng lồ eat 3 slices, the remaining fraction of the pie would therefore be
5
8
as shown in the image to the right. chú ý that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.

Addition:

Unlượt thích adding and subtracting integers such as 2 & 8, fractions require a common denominator to undergo these operations. One method for finding a common denominator involves multiplying the numerators & denominators of all of the fractions involved by the product of the denominators of each fraction. Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator. The numerators also need khổng lồ be multiplied by the appropriate factors lớn 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 khung (the provided aviarus-21.com computes the simplification automatically). Below is an example using this method.

This process can be used for any number of fractions. Just 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 respective denominator) in the problem.

An alternative sầu method for finding a comtháng denominator is to lớn determine the least comtháng multiple (LCM) for the denominators, then add or subtract the numerators as one would an integer. Using the least comtháng multiple can be more efficient & is more likely khổng lồ result in a fraction in simplified form. In the example above, the denominators were 4, 6, và 2. The least comtháng multiple is the first shared multiple of these three numbers.

Multiples of 2: 2, 4, 6, 8 10, 12
Multiples of 4: 4, 8, 12
Multiples of 6: 6, 12

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

EX: 1

Multiplication:

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

Division:

The process for dividing fractions is similar khổng lồ that for multiplying fractions. In order to lớn 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

1

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

Simplification:

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

for example, is more cumbersome than

. The aviarus-21.com provided returns fraction inputs in both improper fraction khung as well as mixed number khung. In both cases, fractions are presented in their lowest forms by dividing both numerator và denominator by their greatest comtháng factor.

Converting between fractions và decimals:

Converting from decimals lớn fractions is straightforward. It does, however, require the understanding that each decimal place to lớn the right of the decimal point represents a power of 10; the first decimal place being 101, the second 102, the third 103, & so on. Simply determine what power of 10 the decimal extends lớn, use that power of 10 as the denominator, enter each number to the right of the decimal point as the numerator, & simplify. For example, looking at the number 0.1234, the number 4 is in the fourth decimal place, which constitutes 104, or 10,000. This would make the fraction

1234
10000
, which simplifies lớn
617
5000
, since the greachạy thử common factor between the numerator & denominator is 2.

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

1
2
for example. To convert this fraction inkhổng lồ a decimal, first convert it inkhổng lồ the fraction of
5
10
. Knowing that the first decimal place represents 10-1,
5
10
can be converted to 0.5. If the fraction were instead
5
100
, the decimal would then be 0.05, và so on. Beyond this, converting fractions inkhổng lồ decimals requires the operation of long division.
