In mathematics, a fraction is a number that represents a part 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 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. ane of those 8 slices would plant the numerator of a fraction, while the total of eight slices that comprises the whole pie would be the denominator. If a person were to swallow 3 slices, the remaining fraction of the pie would therefore be

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

Add-on:

Unlike calculation and subtracting integers such as two and 8, fractions require a mutual denominator to undergo these operations. One method for finding a mutual 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 sure to exist a multiple of each individual denominator. The numerators also need to exist multiplied by the appropriate 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. Yet, in well-nigh cases, the solutions to these equations will not 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. Simply 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 culling method for finding a common denominator is to make up one's mind the to the lowest degree common multiple (LCM) for the denominators, and then add or subtract the numerators as 1 would an integer. Using the to the lowest degree mutual multiple tin can exist more efficient and is more likely to upshot in a fraction in simplified form. In the example above, the denominators were 4, 6, and 2. The to the lowest degree common multiple is the offset shared multiple of these iii numbers.

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

Multiples of 4: 4, 8, 12

Multiples of 6: six, 12

The start multiple they all share is 12, so this is the least mutual 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 same as fraction addition. A mutual denominator is required for the operation to occur. Refer to the addition department equally well as the equations below for clarification.

Multiplication:

Multiplying fractions is fairly straightforward. Unlike adding and subtracting, information technology is not necessary to compute a mutual denominator in guild 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 beneath for clarification.

Partitioning:

The process for dividing fractions is similar to that for multiplying fractions. In club 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 substantially 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:

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

for example, is more cumbersome than

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

Converting between fractions and decimals:

Converting from decimals to fractions is straightforward. It does, however, require the understanding that each decimal identify to the correct of the decimal point represents a power of 10; the offset decimal identify being 10^one, the second 10ⁱⁱ, the tertiary 10³, and so on. Simply determine what power of 10 the decimal extends to, employ that power of 10 as the denominator, enter each number to the correct of the decimal point every bit the numerator, and simplify. For example, looking at the number 0.1234, the number 4 is in the fourth decimal place, which constitutes ten⁴, or 10,000. This would make the fraction

, which simplifies to

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

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

for example. To convert this fraction into a decimal, outset catechumen 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 be 0.05, and and then on. Beyond this, converting fractions into decimals requires the performance of long division.
