I asked ChatGPT these questions and got sensible answers.
How much more is one half than one third?
[subtraction answer: 1/6 more]
That's one possibility, but what about the other way to interpret that question?
[ratio answer, but expressed as "1.5 times as much" rather than "1/2 more"]
Aha, yes. Somehow I forgot the difference interpretation for a moment. Oops!
