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 brand up said whole. For example, in the fraction of

, the numerator is iii, and the denominator is 8. A more than illustrative example could involve a pie with 8 slices. 1 of those viii 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 consume 3 slices, the remaining fraction of the pie would therefore exist

as shown in the epitome to the right. Notation that the denominator of a fraction cannot be 0, as it would brand the fraction undefined. Fractions tin can undergo many dissimilar operations, some of which are mentioned below.

Addition:

Unlike adding and subtracting integers such every bit ii 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 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 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 mutual denominator. Withal, in most cases, the solutions to these equations will non appear in simplified course (the provided reckoner computes the simplification automatically). Below is an example using this method.

This process tin can exist used for whatsoever 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 to the lowest degree mutual multiple (LCM) for the denominators, and so add or subtract the numerators equally one would an integer. Using the least common multiple can be more than efficient and is more probable to upshot in a fraction in simplified form. In the example above, the denominators were 4, 6, and ii. The least common multiple is the starting time shared multiple of these iii numbers.

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

Multiples of 4: 4, 8, 12

Multiples of 6: vi, 12

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

Subtraction:

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

Multiplication:

Multiplying fractions is fairly straightforward. Different adding and subtracting, it is non necessary to compute a common denominator in club 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 exist simplified. Refer to the equations below for clarification.

Division:

The process for dividing fractions is similar to that for multiplying fractions. In society to split up fractions, the fraction in the numerator is multiplied past 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 be

. Refer to the equations below for clarification.

Simplification:

Information technology is often easier to work with simplified fractions. As such, fraction solutions are ordinarily expressed in their simplified forms.

for example, 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 everyman 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, even so, crave the agreement that each decimal place to the correct of the decimal point represents a power of 10; the first decimal place beingness x^ane, the second 10², the tertiary ten^three, so on. Just determine what ability of x the decimal extends to, use that ability of 10 as the denominator, enter each number to the correct of the decimal betoken every bit the numerator, and simplify. For case, looking at the number 0.1234, the number 4 is in the fourth decimal place, which constitutes 10⁴, or ten,000. This would brand the fraction

, which simplifies to

, since the greatest mutual gene between the numerator and denominator is ii.

Similarly, fractions with denominators that are powers of 10 (or can exist converted to powers of 10) can be translated to decimal class using the aforementioned principles. Have the fraction

for example. To convert this fraction into a decimal, offset convert information technology 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 so on. Beyond this, converting fractions into decimals requires the functioning of long division.
