<Li> Spelled - out fractions are hyphenated: seven - eighths . </Li> <Li> Where numerator and denominator can each be expressed in one word, a fraction is usually spelled out (e.g. a two - thirds majority; moved one - quarter mile); use figures if a fraction appears with a symbol (e.g. ⁄ mi--markup: ((frac 1 4)) &nbsp; mi, not a quarter of a mi or one - quarter mi). A common exception is a series of values: The distances were 1 ⁄, ⁄ and ⁄ mile, respectively . </Li> <Li> Mixed numbers are usually given in figures, unspaced (not Fellini's film 8 ⁄ or 8 - ⁄ but Fellini's film 8 ⁄--markup: ((frac 8 1 2))). In any case the integer and fractional parts should be consistent (not nine and ⁄). </Li> <Li> Metric (SI) measurements generally use decimals, not fractions (5.25 mm, not 5 ⁄ mm). </Li>
