The Cardinals

§ 229. Amongthe cardinals there aresimple, derived, andcompoundwords.

The cardinals from one to twelve, hundred, thousand, million are simple words; those from thirteen to nineteen are derived from the corresponding simple ones by means of the suffix -teen; the cardinals denoting fens are derived from the corresponding simple ones by means of the suffix -ty.

Note:

Mind the difference in the spelling of the stem in three and thirteen (thirty), four and forty, five and

fifteen (fifty).

The cardinals from twenty-one to twenty-nine, from thirty-one to thirty-nine, etc. and those over hundred are compounds.

In cardinals consisting of tens and units the two words are hyphenated:

21 - twenty-one,

35 - thirty-five,

72 - seventy-two, etc.

In cardinals including hundreds and thousands the words denoting units and tens are joined to those denoting hundreds, thousands, by means of the conjunction and:

103 - one hundred and three,

225 - two hundred and twenty-five,

3038 - three thousand and thirty-eight,

The words for common fractions are also composite. They are formed from cardinals denoting the numerator and substantivized ordinals denoting the denominator. If the numerator is a numeral higher than one, the ordinal in the denominator takes the plural form. The numerator and denominator may be joined by means of a hyphen or without it:

1/3 - one-third (one third),

2/7 - two-sevenths (two sevenths), etc.

In mixed numbers the numerals denoting fractions are joined to the numerals denoting integers (whole numbers) by means of the conjunction and:
