Can the sum of two mixed numbers be equal to 2? explain why or why not.

No it cannot because a mixed #  for example would look like this 2 3/5 it will need a whole number and a fraction
The reason why I say NO is because you can only have 1 mixed number in 2 and that would be 1 1/2 (1 1/2 + 1/2 = 2) And when you try again your numbers will be 1 and 1. So NO, you cannot have to mixed numbers in the number 2
