Answer:
2/7
Explanation:
First off you would want to get rid of the negative because a negative times a negative equal a positive making the -2/3 and -6/7 a positive then you would want to cancel out the greatest common factor of 2 making the equation now 1/3 x 6/7 then you'll want to cancel out the greatest common factor of 3 by dividing 3 by 3 and 6 by 3 making it 1/1 x 2/7 and then after you multiply you get your answer of 2/7
