Numerical fractions written in Arabic script

[Robert Wheelock]

Hello again, y’all!

How do Arabs, Iranians, Afghans, Pakistanis, Urdu ... all write their
equivalents of common numerical fractions (consisting of a numerator, a
separator character, and a denominator)?!?!
Considering that Arabic written script reads from right to left (like in
Hebrew, Syro-Aramaic, and the fantasy language of Tsolyáni), would they use
a normal right-facing foreslash (1/2), a left-facing backslash (1\2), or do
they align numerator above|demoniator below a horizontal fraction bar?!?!
Notice that these people would use the native Arabic-based digits in them;
nonewithstanding, the forms for |4 5 6| (and—sometimes—those for |2 7|) do
look quite different from the canonical Arabic forms.

Just something to think about...
Thank You!
