Think about the different ways we say numbers, such as "and" where "and" isn't actually supposed to be, or "point (cardinal number)" when one should normally use "and (ordinal number)" for any number that is not an integer and is a real.
So some may use the suffixes after all the numbers, and some may say them after the first number.
An example, in my head I hear "one hundred and thirty seven point forty two". If someone were to say "one hundred thirty seven and forty seconds", I'd be completely lost.
So, #-Ꮛ/Ꮚ ##, could be the same as ###-Ꮛ/Ꮚ
