Question

Can the sum of two mixed number be equal to 2

Answer 1

Not unless you use negative mixed numbers.

-1 1/2 + 3 1/2 =2

Answer 2

No, because each mixed number must have at least 1 and a fraction
Like this:

1 1/4 + 1 1/16 = more than 2
1 + 1 = 2

Therefore, you can't have 2 mixed numbers without the sum being greater than 2
Hope this helped!
