GrammarFractions and Decimals

Fractions and Decimals

Russian fractions are a "grammar sandwich": The numerator is a cardinal number, and the denominator is an ordinal number.

  • - one half
  • - two thirds
  • - three quarters

The "Half" Family: There is пол- (half), полови́на (a half), and the very common полтора́ (one and a half). Note that полтора́ has its own unique declension!

  • - half an hour
  • - half of the house
  • (masc/neut) - one and a half hours
  • (fem) - one and a half minutes
  • - with one and a half hours
  • - to one and a half days

Decimals: Russians use a comma rather than a point (e.g., 1,5 instead of 1.5).

  • 1,5 → - "one whole five tenths"
  • 2,75 → - "two whole seventy-five hundredths"

Case Agreement: Fractions govern the Genitive Singular — the noun names the whole that the fraction is taken from.

  • → Genitive Singular
  • → Genitive Singular
  • → Genitive Singular
