You can enter the percentage number in a cell of your choice, copy that cell, then hilite the numeric data cells you mention, and click Edit > Paste special > select "Add" in the Operation section, and click OK.

Well, i don't know if this help you, but try this...
First, in another sheet, type 100.
Second, copy this value, go to the sheet that you want, select edition - go to - special, and select constants.
Next, select edition - paste special - operation - divide.
Next, click on the "%" button on the format toolbar.
Now, again, select edition - go to - special, and select formulas and choose ONLY Numbers.
Edition - Paste special - Operation - Divide.
And click on the "%" button on the tool bar...
That should.. i think... do it.
Any help ?
