§Noun

fraction (plural fractions)

1. A part of a whole, especially a comparatively small part.

     With fresh material, taxonomic conclusions are leavened by recognition that the material examined reflects the site it occupied; a herbarium packet gives one only a small fraction of the data desirable for sound conclusions. Herbarium material does not, indeed, allow one to extrapolate safely: what you see is what you get […]

2. A ratio of two numbers, the numerator and the denominator, usually written one above the other and separated by a horizontal bar.
3. (chemistry) A component of a mixture, separated by fractionation.
4. In a eucharistic service, the breaking of the host.

   • 1898, Winston Churchill, chapter 2, The Celebrity:

     I had occasion […] to make a somewhat long business trip to Chicago, and on my return […] I found Farrar awaiting me in the railway station. He smiled his wonted fraction by way of greeting, […], and finally leading me to his buggy, turned and drove out of town.

   • 2011 January 29, Chris Bevan, “Torquay 0-1 Crawley Town”, BBC:

     After kick-off was delayed because of crowd congestion, Torquay went closest to scoring in a cagey opening 30 minutes, when Danny Stevens saw a fierce shot from the edge of the area swerve a fraction wide.

6. The act of breaking, or state of being broken, especially by violence.
   • Foxe
