Halves, thirds, quarters, eighths and the rest — as single characters you can copy.
These are precomposed fractions — each one is a single Unicode character, not a "1", a slash and a "2" stuck together — so they line up neatly in recipes, measurements, spreadsheets and posts without throwing off the line height. They cover the common cooking and tape-measure fractions (halves, quarters, thirds, eighths). For a fraction that doesn't exist as a single character, the fraction slash (⁄) joins a numerator and denominator into a proper-looking fraction in fonts that support it, or you can write it inline as 5/16. For built-up fractions in documents, a word processor's equation editor is the more flexible route.
