Not smarter; there's a list somewhere. Extracted:
2150 VULGAR FRACTION ONE SEVENTH
# <fraction> 0031 2044 0037
2151 VULGAR FRACTION ONE NINTH
# <fraction> 0031 2044 0039
2152 VULGAR FRACTION ONE TENTH
# <fraction> 0031 2044 0031 0030
2153 VULGAR FRACTION ONE THIRD
# <fraction> 0031 2044 0033
then as quoted above, and, knocking around:
2189 VULGAR FRACTION ZERO THIRDS
* used in baseball scoring, from ARIB STD B24
# <fraction> 0030 2044 0033
Cheers,
David.
