Mixed numerals are counting numerals which are composed of a cardinal numeral and a fraction numeral.
a. Syntax of Mixed Numerals
The two components of the mixed Numeral are coordinated with the conjunction /o/:
دو و سهپنجم /do vo se-pænʤom/
بیست و سههفتم /bist o se-hæftom/
The noun phrases /nesf-i/ نصفی ([NP[NP/nesf/] [Denclitical article /-i/]]) and /nim/ نیم can be used like a fraction numeral in the syntax of fixed numerals:
بیست و پنج و نصفی /bist o pænʤ o nesf-i/
ده و نیم /dæh o nim/
b. Pattern of Numeral Phrases with Mixed Numerals
To generate Persian numeral phrases with mixed numerals, one must first construct a numeral phrase with the cardinal component, and coordinate it by means of conjunction /o/ with the fraction component.
Hence, the pattern of such numeral phrases is [NP[NP[DetPcardinal numeral] [NPnoun phrase]] [Conconjunction /o/] [NPfraction numeral]]:
پنج کیلو و دوسوم /pænʤ kilu o do-sevvom/
سه سال و نیم /se sɒl o nim/
