### Strange Mixed Decimal/Fraction Notation

Has any one seen a notation like the following examples actually being used:

Code: Select all

`                 2               12-    2            3                 190.12- meaning ----- or simplified ---    3          100                150               1              5-   1           3                 80.5- meaning ---- or simplified --   3          10                15   3          110.2- yielding --   4          40`

Note that I have done without LaTeX or Unicode there: the notation in the book actually looked closer to: $0.12\tfrac{2}{3}$

I have never seen such a notation except in the one case of the mathematics book I am getting these examples from, and I question whether it is has ever been used in practice.

### Re: Strange Mixed Decimal/Fraction Notation

Personally I've never seen such a notation. So it is certainly not any kind of "standard".

It does make sense, though, in its own twisted way. It's exactly the kind of thing you'll expect a math-oriented person to invent in his spare time and use for his own needs. It shouldn't be in a textbook, though, unless the book clearly states that it isn't a standard notation.
