Import data" utility in TOAD

Question

Hi,
I have converted data from Microsoft Excel into Oracle table using TOAD 10.6 version "Import data" utility. It is converting data from fraction to decimal but I want data in fractions in my Oracle table. Please let me know how it can be done.
Import data utility result

1.01   -1/2         1/4     3/4      1 3/4Thanks
Sandy
