Wow I have overworked thinking about this. I have settled on just presenting all fractions horizontal. The only ones I will present spatially are the ones that show something in the nominator and denominator such as

• 2×2     4
• —  — = —
• 3×2     6

Otherwise I will show
<ol start=”8″>

• +⅓   + 2/7    +⅗
• —-   ——    —-

Please see attached file for translated braille version. Sorry I spent so much time talking myself  through this.
