The sum of two positive mixed numbers can not equal two because all positive mixed numbers are greater then one.no two can be, 1 1/2 and 1/2
There is only one mixed number equal to 7.5 . It is 71/2 .
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!
There is only one example where the sum of two mixed numbers can be equal to two. 1/1 + 1/1 All other combinations of mixed numbers will be greater than two.
1 & 1/2
