On ordinal number usage:

• Ordinal numbers are generally construed as adjectives preceding (countable) nouns in singular:
eleventh day
• Ordinal numbers are used for fractions as (countable) nouns, and for exponents usually followed by power and that numeral:
two fifths, $\textstyle {\frac {2}{5}}$ two to the minus twenty-first power, $2^{-21}$ six to the third, $6^{3}$ • Ordinal numbers are generally considered to be ordered from high to low, so that first place is considered highest, and fifth is lower than second. Degree is an exception.
• Ordinal numbers corresponding to numbers higher than 20 use cardinal numbers for all the places preceding the final ordinal part:
twenty-first or 21st, occasionally XXI
one hundred fifteenth or 115th, occasionally CXV
thirty-three thousandth or 33,000th
• If an ordinal is followed by a plural noun, the two word phrase refers to a set of items described by the phrase in singular. For example second homes refers to a set of homes which are considered a "second home."
Many households have third cars.
