Fraction


Definition:

  • (n.) The act of breaking, or state of being broken, especially by violence.
  • (n.) A portion; a fragment.
  • (n.) One or more aliquot parts of a unit or whole number; an expression for a definite portion of a unit or magnitude.
  • (v. t.) To separate by means of, or to subject to, fractional distillation or crystallization; to fractionate; -- frequently used with out; as, to fraction out a certain grade of oil from pretroleum.
