To subtract the fractions, we first need to find a common denominator. In this case, both fractions already have the same denominator of 13.
So, we can subtract the numerators(-8 7/13) + (2 4/13) = -8 + 2 + 7/13 + 4/1= -6 + 11/13
Now we can divide the result by -3(-6 + 11/13) ÷ (-3= -6 ÷ (-3) + 11/13 ÷ (-3= 2 - 11/39
Therefore, the final answer is 2 - 11/39.
