I am trying to add in percentages into a mail merge. I have see other posts saying to press ALT F9 to create a mergefield and then add *100#0% and then toggle twice.
I'm not too sure how to toggle twice or if this is the correct way to go about getting a percentage instead of the long 0.9853564646E-2
I have tried researching how to fix this but can't find a solution

It all depends on how the data is in Excel, to some extent.
Alt+F9 toggles display of field codes. Many computers have hijacked the function keys for proprietary uses and require the addition of the Fn shift key.
You would want something like:

Remember, when you are done editing your field, press Alt+F9 again to toggle display back to field results.
