Thank you for ur help!
Tableau treats data more like a database does, and one of the things databases do is separate data types from display formats, so when transferring data from a data source to Tableau the only thing that is transferred is the data type. For data types Tableau knows about numbers (decimal and whole), strings/text, booleans (yes/no true/false 1/0), dates, and datetimes.
Under the hood Excel separates data types from display formats, but all we typically see in Excel is the single formatting set of options. Since the Benchmark and Current Rate columns in Excel are defined as decimal numbers they are brought into Tableau as decimal numbers and that's what you're seeing. You'll need to define how you want the numbers defined in Tableau. In the Dimensions and Measures windows you can right-click on fields and choose Default Properties->Number Format... to change the default number formatting.
