Answer:1 -3/-6
Explanation:
simplify 1 2/3 to 5/3 making it:
5/3 + 3/4 divided by -1/3 - 1/2
then make the denominator the same for all fractions:
5/3+3/4=9+6/12= 15/12
do the same for the next fraction making it -5/5
15/12 divided by -5/6= 90/-60 (by using keep, change, flip)
into a mixed number-> 1 -3/-6
