I sometimes read newspapers aloud to practice pronunciation, but encounter the issue of percentage points, e.g. 20% and 31% differ by "11 percentage points" (or just "11 points" for brevity). For a concrete example, I recently encountered this:
I'm unsure how to pronounce "11%" here. The obvious thing to say is 百分之十一, but I'm worried that might be incorrect because it's referring to percentage points.
Question: How do you read "11%" aloud when it refers to percentage points?
