Right-click on one of the SUM(Number of Records) pills on the Marks Card and choose Format... In the Format window that appears click on the Pane tab->Default section->Numbers and change the number format to Percent with 1 decimal place.
STEP 1 — Click on the SUM([Number of Records]) on the Marks shelf (the one used for "Angle") and then click Format.
STEP 2 — On the "Pane" tab of the Format panel on the left, under the section "Default", click the drop-down next to "Numbers".
STEP 3 — Click on Percentage, then adjust the number of decimal places on the right-hand side.
That should do it!
