You made a sign error.

-1%262%2F3%22%22-%22%22%28-1%264%2F11%29 

When you have "minus a negative" you can replace it by
"plus a positive"

-1%262%2F3%22%22%2B%22%22%281%264%2F11%29

Multiply the 2%2F3 by 11%2F11 to get 22%2F33
Multiply the 4%2F11 by 3%2F3 to get 12%2F33

-1%2622%2F33%22%22%2B%22%22%281%2612%2F33%29 

The signs are different so we subtract the absolute values
    
         %281%2622%2F33%29%22%22-%22%22%281%2612%2F33%29%22%22=%22%2210%2F33 

BUT, we MUST take the sign of the one with the larger absolute
value which is -1%2622%2F33 so the answer must be NEGATIVE:

Answer: -10%2F33
