I want help phrasing the instructions in a math question. The issue is the correct way to express mixed units.
For example, if an answer is “25 inches,” I don’t want to accept “25 inches” or “1 foot 13 inches,” but only “2 feet 1 inch.”
I guess you might say that I want the total number of units to be small as possible. But I don’t think anyone would understand what I meant by that. Similarly, I don't think it would do to say that I want the answer "simplified."
