If you're measuring a room and need the square footage for some home project, would be one example.
Say your room is 17 feet 3 inches by 13 feet 4 inches, and you need the square feet. You can express this as (17 3/12) feet x (13 4/12) feet, or you could convert to inches: 17 x 12 + 3 = 207 inches, and 13 x 12 + 4 = 160 inches, then multiply to get 33120 sq.in, then divide by 144 to get sq.ft = 230 sq.ft
Or you could leave them as mixed fractions: (17 + 3/12)(13 + 4/12) and multiply them to get 230 sq.ft

you cant divide mixed numbers
Why the set of mixed numbers is not a subset of the set of integers?
Mixed numbers and integers are different things.
In what situation would not be a good idea with estimating mixed numbers?
it would not be a good time to estimate mixed numbers is when both of the fractions are not a mixed number
Why can't two mixed numbers be equal to 2?
The question is misguided because, in fact, two mixed numbers can be added to equal 2. For example: 31/2 and (-11/2), when added together, give 2. There is no reason to restrict mixed numbers to positive mixed numbers!
