use
The sign ¼ stands for the fraction fraction 1 divided by 4, i.e. the decimal number 0.25. It is used primarily in texts; In mathematical formulas one usually writes with a horizontal fraction line.
Correct spelling is, for example, “¼ to 5 o'clock”, but “the ¼ character, the ¼ note and the ¼ em distance” are coupled through . Grammatical diffraction is not affixiert : (read "about a" in about ¼ of the cases' em quarter of cases ").
The earliest evidence for the spelling of elementary stem and branch breaks (common fractions) with a slanted fraction line can be found in the small treatise De Thiende ( Eng . 'The Tenth') by Simon Stevin from 1585.

The straight line notation is not available in the Unicode character set and can be set with TeX :\textstyle \frac{1}{4}
or short\tfrac{1}{4}
. Conversely, TeX allows the spelling with an inclined fraction only with great effort.
