Question 1121485
.
<pre>
If one mixed number is "x", then the other mixed number is 6 - x.


In this way, taking any mixed number as "x", you obtain the other mixed number 6-x so that their sum is 6.


There are infinitely many solutions.


For example, these pairs (5,1), (4,2),  ({{{3}}}{{{1/2}}},{{{2}}}{{{1/2}}}), (7,-1), (-2,8), and so on . . .
