No.
A positive mixed number must be bigger than one: so each of them must be of the form one-and-some-more. Therefore, their sum must be two and the sum of two some-more bits, which must be more than 2.
When the sum of the negatives is an integer is when the sum is a whole number
Not only could they be, but they always are.
Yes
Yes
Yes it can. Consider the numbers 31/2 and negative 11/2. Their sum is 2. So the question is misguided.
Yes. Mixed numbers can be negative. -11/2 + 31/2 = 2

It can't be one. Negative mixed numbers are less than negative one.
It can't be one. Negative mixed numbers are less than negative one.
It can't be one. Negative mixed numbers are less than negative one.
Not only could they be, but they always are.
no
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!
There is only one mixed number equal to 7.5 . It is 71/2 .
It can't be one. Negative mixed numbers are less than -1.
No.
