what tab for calculating percent and decimal?

[Heidi]

I want to find the percent for each column. Which tab do I click to get the
drop down choice for percent. I found it once and forgot to remember it. I
also remember seeing the dropdown had decimal as well. I am just starting to
explore using this for my grading system at school. Today is my first day
exploring this site.
