Answer:
Place the dot in the middle of -1 and -2!
Explanation:
You have to add 2 -2 2/6 and 5/6 that will get you -1 3/6. Then you have to find where it goes. If you would simplify the number you would get -1 1/2. This means the dot would be placed in the middle of 2 numbers. Since it is 1 and 1/2 you would need to place it between -1 and -2.
Hope this helps!
