Character 1/2, 1/3

[Martin Adorni]

Hi,

writing a text I came across a maybe simple problem. Is there a special
character to write 1/2, 1/3 and so on. To be more precise: Im looking
for ONE character giving me an upper 1 followed by / and a lower 2.
I've tried this in math mode but it didn't look well.

Any suggestions are welcome.

Martin
