In mathematics, a portion 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 components of a whole, when the denominator is the total number of parts that make up said whole. For example, in the fraction of
 3 8
, the numerator is 3, and the denominator is 8. A more illustrative example can involve a pie v 8 slices. 1 the those 8 slices would constitute the numerator of a fraction, when the total of 8 slices that comprises the entirety pie would certainly be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would because of this be
 5 8
as presented in the photo to the right. Note that the denominator of a fraction cannot it is in 0, together it would certainly make the fraction undefined. Fractions have the right to undergo plenty of different operations, some of which are pointed out below.

Unlike including and individually integers such together 2 and also 8, fractions call for a common denominator to undergo these operations. One an approach for finding a typical denominator involves multiplying the numerators and also denominators of all of the fractions associated by the product the the denominators of each fraction. Multiplying every one of the denominators ensures the the new denominator is particular to be a many of every individual denominator. The numerators likewise need to be multiplied by the proper factors to maintain the worth of the fraction as a whole. This is may be the simplest means to ensure the the fractions have a usual denominator. However, in most cases, the remedies to this equations will not appear in simplified form (the detailed neurosoup.org computes the simplification automatically). Below is an example using this method.

 a b
+ c
d
= a×d
b×d
+ c×b
d×b
bd
 EX: 3 4
+ 1
6
= 3×6
4×6
+ 1×4
6×4
= 22
24
= 11
12

This procedure can be provided for any variety of fractions. Simply multiply the numerators and denominators of each portion in the trouble by the product of the platform of every the various other fractions (not consisting of its very own respective denominator) in the problem.

 EX: 1 4
+ 1
6
+ 1
2
= 1×6×2
4×6×2
+ 1×4×2
6×4×2
+ 1×4×6
2×4×6

An alternative method for recognize a usual denominator is to recognize the least usual multiple (LCM) because that the denominators, then add or subtract the numerators together one would certainly an integer. Making use of the least common multiple deserve to be an ext efficient and is an ext likely to an outcome in a portion in simplified form. In the example above, the denominators were 4, 6, and 2. The least usual multiple is the first shared lot of of these three numbers.

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

The very first multiple they all share is 12, for this reason this is the least common multiple. To complete an addition (or subtraction) problem, main point the numerators and also denominators the each fraction in the trouble by whatever value will make the denominators 12, then include the numerators.

 EX: 1 4
+ 1
6
+ 1

= 1×3
4×3

### Subtraction:

Fraction individually is essentially the same as fraction addition. A common denominator is forced for the operation to occur. Refer to the enhancement section and also the equations listed below for clarification.

### Multiplication:

Multiplying fountain is reasonably straightforward. Unlike adding and subtracting, it is not important to compute a usual denominator in order to multiply fractions. Simply, the numerators and also denominators of each portion are multiplied, and also the result forms a new numerator and also denominator. If possible, the solution should be simplified. Describe the equations listed below for clarification.

 a b
× c
d
= ac

 EX: 3 4
× 1

### Division:

The procedure for splitting fractions is comparable to the for multiply fractions. In stimulate to division fractions, the fraction in the molecule is multiplied by the reciprocal of the portion in the denominator. The reciprocal of a number a is simply
 1 a
. When a is a fraction, this essentially entails exchanging the place of the numerator and also the denominator. The reciprocal of the portion
 3 4
would because of this be
 4 3
. Describe the equations below for clarification.

 a b
/ c
d
= a

 EX: 3 4

### Simplification:

It is often simpler to job-related with streamlined fractions. Together such, portion solutions are typically expressed in their simplified forms.
 220 440
because that example, is much more cumbersome than
 1 2
. The neurosoup.org listed returns fraction inputs in both not correct fraction form as fine as mixed number form. In both cases, fractions are presented in their lowest forms by separating both numerator and also denominator by your greatest typical factor.

### Converting between fractions and also decimals:

Converting from decimals to fractions is straightforward. That does, however, call for the understanding that every decimal place to the best of the decimal point represents a power of 10; the first decimal place being 101, the second 102, the 3rd 103, and also so on. Simply determine what power of 10 the decimal extends to, use that power of 10 as the denominator, enter each number to the ideal of the decimal allude as the numerator, and also simplify. Because that example, looking at the number 0.1234, the number 4 is in the fourth decimal place, which constitutes 104, or 10,000. This would certainly make the portion
 1234 10000
, i m sorry simplifies come
 617 5000
, because the greatest common factor between the numerator and also denominator is 2.

Similarly, fractions v denominators that room powers that 10 (or deserve to be convert to strength of 10) have the right to be interpreted to decimal kind using the exact same principles. Take it the fraction
 1 2
because that example. To transform this fraction into a decimal, very first convert it right into the portion of
 5 10
. Discovering that the first decimal place represents 10-1,
 5 10
can be converted to 0.5. If the portion were instead
 5 100
, the decimal would certainly then it is in 0.05, and also so on. Beyond this, converting fractions right into decimals needs the operation of lengthy division.
