"Le français est parlé couramment par ________ 200 millions de personnes dans le monde."
French language is spoken by more than 200 million people around the world.
I put "plus que" since that felt like "more than" but the correct answer is "plus de." I'm struggling to understand this since it doesn't fit the same structure as the lesson examples (e.g. French is spoken by more people than Italian).
Thanks for any clarification!
