The answer is: " -5/3 " ; or, write as: " -1 ⅔ " .
_____________________________________________
Explanation:
_____________________________________________
(-5/6) + (-5/6) = (-5/6) <span>− (5/6) ;
------> {since: "adding a negative" is the same a "subtracting a positive"} ;
------> </span> (-5/6) − (5/6) = (-5 − 5) / 6 ;
= -10/6 = (-10/2) / (6/2) ;

= " -5/3 " ; or, write as: " -1 ⅔ " .

It seems to be none of the above
Make the denominator the same, so multiple 3/10 by 2, which produces 6/20. Take 6/20 and subtract 7/20 because adding a negative number is the same as subtracting a positive number. the Answer is -1/20.
