Answer:
Step-by-step explanation:
Please type numerals and punctuation for your mixed numbers.
I will have to assume that you meant 2 5/6 and 1 1/3, and that you are subtracting 2 5/6 from - 1 1/3. If that is correct, then we determine the LCD and rewrite -1 1/3 using this LCD:
-1 1/3 -1 2/6
-2 5/6 -2 5/6
----------
-3 7/6 or -4 1/6
The best calculation of this difference is -4 1/6 and the best estimate is
-1 - 3, or -4
