Answer:
The answer is in the first one -6 3/4(I think that is what you mean) and and the other one is 2/3
Step-by-step explanation:
In the first one you can do is find a common denominator which would be 12 so to get to 12 with the second number you have to do 6x3/4x3 which equals 6 9/12 so it would be 6 9/12> 6 7/12.
For the next one it is obvious because 2/3 is positive while -5/6 is negative and positives are greater then negatives but if you meant positive 5/6 then you would first have to find a common denominator which would be 6 so it would be 2x2/3x2 which equals 4/6 so it would be 4/6<5/6
