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

 3 8
, the numerator is 3, và the denominator is 8. A more illustrative 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 to lớn eat 3 slices, the remaining fraction of the pie would therefore be
 5 8
as shown in the image lớn the right. Note 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.

Unlike adding & subtracting integers such as 2 và 8, fractions require a common denominator khổng lồ undergo these operations. One method for finding a comtháng denominator involves multiplying the numerators & denominators of all of the fractions involved by the hàng hóa of the denominators of each fraction. Multiplying all of the denominators ensures that the new denominator is certain to lớn be a multiple of each individual denominator. The numerators also need to lớn be multiplied by the appropriate factors khổng lồ preserve the value of the fraction as a whole. This is arguably the simplest way to lớn ensure that the fractions have sầu a common denominator. However, in most cases, the solutions khổng lồ these equations will not appear in simplified size (the provided chienquoc.com.vn computes the simplification automatically). Below is an example using this method.

 EX: 3 4

6

4×6
+ 1×4
6×4

This process can be used for any number of fractions. Just multiply the numerators và 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 common denominator is khổng lồ determine the least common 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 result in a fraction in simplified khung. In the example above sầu, the denominators were 4, 6, & 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 nói qua is 12, so this is the least comtháng multiple. To complete an addition (or subtraction) problem, multiply the numerators và denominators of each fraction in the problem by whatever value will make the denominators 12, then add the numerators.

 EX: 1 4
+ 1

### Subtraction:

Fraction subtraction is essentially the same as fraction addition. A comtháng denominator is required for the operation khổng lồ occur. Refer to the addition section as well as the equations below for clarification.

### Multiplication:

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

### Division:

The process for dividing fractions is similar lớn 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

 1 a
. When a is a fraction, this essentially involves exchanging the position of the numerator & the denominator. The reciprocal of the fraction
 3 4
would therefore be
 4 3
. Refer lớn the equations below for clarification.

### Simplification:

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

 220 440
for example, is more cumbersome than
 1 2
. The chienquoc.com.vn 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 greademo common factor.

### Converting between fractions và decimals:

Converting from decimals to fractions is straightforward. It does however require the understanding that each decimal place to the right of the decimal point represents a power of 10; the first decimal place being 101, the second 102, the third 103, và so on. Simply determine what power of 10 the decimal extends lớn, use that power of 10 as the denominator, enter each number khổng lồ the right of the decimal point as the numerator, and 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 greademo comtháng factor between the numerator & denominator is 2.

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

 1 2
for example. To convert this fraction into a decimal, first convert it into the fraction
 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, & so on. Beyond this, converting fractions inlớn decimals requires the operation of long division.
