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 instance, in the fraction of

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

equally shown in the image to the right. Notation that the denominator of a fraction cannot be 0, equally it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.

Addition:

Unlike calculation and subtracting integers such as 2 and eight, fractions crave 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 sure to be a multiple of each individual denominator. The numerators also demand to be multiplied by the appropriate factors to preserve the value of the fraction as a whole. This is arguably the simplest fashion to ensure that the fractions have a common denominator. However, in most cases, the solutions to these equations will not announced in simplified class (the provided calculator computes the simplification automatically). Below is an example using this method.

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

An culling method for finding a common denominator is to make up one's mind the least common multiple (LCM) for the denominators, then add together or subtract the numerators as one would an integer. Using the to the lowest degree mutual multiple can be more than efficient and is more than likely to result in a fraction in simplified form. In the instance above, the denominators were four, six, and 2. The to the lowest degree common multiple is the showtime shared multiple of these three numbers.

Multiples of two: two, 4, half dozen, 8 ten, 12

Multiples of 4: 4, viii, 12

Multiples of 6: vi, 12

The first multiple they all share is 12, then this is the least common multiple. To complete an add-on (or subtraction) trouble, multiply the numerators and denominators of each fraction in the problem by any value volition make the denominators 12, then add the numerators.

Subtraction:

Fraction subtraction is essentially the same every bit fraction addition. A common denominator is required for the functioning to occur. Refer to the add-on department every bit well every bit the equations below for description.

Multiplication:

Multiplying fractions is fairly straightforward. Unlike adding and subtracting, it 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 effect forms a new numerator and denominator. If possible, the solution should be simplified. Refer to the equations below for clarification.

Division:

The process for dividing fractions is similar to that for multiplying fractions. In order to split up fractions, the fraction in the numerator is multiplied by the reciprocal of the fraction in the denominator. The reciprocal of a number a is merely

. 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:

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

for example, is more than cumbersome than

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

Converting between fractions and decimals:

Converting from decimals to fractions is straightforward. It does, still, require the agreement that each decimal identify to the correct of the decimal point represents a power of 10; the first decimal place existence 10¹, the 2nd ten², the third 10^three, and so on. Just decide what power of x the decimal extends to, employ that ability of 10 as the denominator, enter each number to the right of the decimal bespeak 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 10⁴, or x,000. This would make 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 10 (or can exist converted to powers of 10) can exist translated to decimal form using the same principles. Have the fraction

for example. To convert this fraction into a decimal, first convert it into the fraction of

. Knowing that the first decimal place represents 10^-1,

can exist converted to 0.v. If the fraction were instead

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