If you don't need Excel to recognize the fractions as numbers for AutoSum, you can select the cells in question and go format->cells->text. However, if you do need Excel to recognize the fractions as numbers for manipulation, go format->cells->fraction, and select ''up to three digits.'' As long as the numerator and denominator are both between -999 and 999 you're fine...it will remain exactly as you enter it. Otherwise they'll be converted into mixed fractions. Unfortunately that's the best you can do with what you got.
Hope this helps,

Hi,
Whenever I enter fractions such as 4/8 or 2/4 Excel reduces them to the lowest possible. Is this really automatic? Where are the controls for this function?
Thanks,
