Numeric fractions, where both numerator and denominator are positive integers are represented as follows:
The numerator is written in standard (upper) notation and the denominator in the lowered notation without its own number character and without additional spaces.
Note: One can take a mixture of numerical fractions with fractions in mathematical expressions combined in simple or detailed notation, so one can also use numerical fractions the appropriate format can be chosen to make all fractions uniform.
Both components of a mixed number, the integer and the numerical fraction, are provided with a number sign, spaces between them.
Comes neither in the numerator nor in the denominator of a fraction Spaces, may be used to indicate the arrival and refrained from leading to broken offenses (see "9.3 Full fraction notation \. The symbol for the fraction line is \ immediately follows the numerator. Also denominator comes next with any spaces.
This simplified notation is also allowed where empty sign in numerator or denominator by the cohesion point @, which is not suitable for complex Expressions by the suppression of voids become confusing.
Excluding numerical and other simple fractions, the mandatory terminology (see "9.1 Numeric fractions and mixed numbers" and "9.2 Simple fractional wise"), especially if:
The fraction is made with the fraction start character 2 initiated which is immediately before the denominator. The fraction terminator ; completes the denominator.
In terms of spaces, the fraction start and end fraction sign are like brackets.
The symbol for the fraction line \ stands between numerator and Denominator. Generally it will be on both sides of spaces surround. The two spaces may only be omitted if there is no space in either the numerator or the denominator occurs. It can not keep a space and up the other will be omitted.
The fraction start character must not without the fraction end character used and vice versa, but see "9.4 Multiple fractions "for the completion of fractions of fractions.
For example, if the fractional start character is immediately behind symbol and confused with the mark symbol for point 2 or the number 2 in lowered. You can place between these characters Cohesion dot @ inserted (see "8 Simple and summary markings").
If a letter follows the fraction end character, this may not confused with the indicator for Greek letters. can be. Therefore, a Latin lowercase letter following the fraction end sign with point 6 , terminates and between the end of the fraction and the indicator for capital letters the cohesion point @ adds (see "1.2 Separating and holding together mathematical Expressions" as well as examples 3.2 B06 and 11.3 B04).
Note: Contrary to previous practice, all numbers must be immediate written after the fractional stroke in the standard notation (see "2.1.1 numbers in standard notation").
When interleaving fractions must be analogous to the mathematical bracket rules each fraction individually with one start fractionn character and initiate with a fraction sign to be completed.
Ends all initiated fractions in the same place, the Row of fraction end characters by the sign for the all fractions =; are replaced.
Even fractions of positive integers are allowed within other fractions written in the usual spelling (see "9.1 Numeric fractions and mixed numbers"). Also Fractions in the simple fractional writing are possible, however Use only with great caution.
The instructions for fractions are a bit muddy. Here is my take:
