Fractions question

[_catherine_a_lucas_]

I am working on a big job, that is completely layouted. Now they decided they want the available fractions in the layout in real fractions, as in smaller type with the slash...
The font I used is Arial Narrow, and that font is not open type and does not have fractions available...
Is there another way of doing fractions? There is around 3000 in the layout, so I would be grateful not to have to do them manually...
Changing font would be the last but in no other solution way the latest...
I am dutch speaking, forgive me for spelling mistakes

Thanks in advance for any input...

Instead of Arial Narrow, use an Opentype font that supports fractions. Adob Myriad condensed Pro should work.
