Answer:

B -11 4/15

Step-by-step explanation:

-7 3/5 -3 2/3 = -(7 3/5 +3 2/3)

= -((7 +3) +(3/5 +2/3)) = -(10 +9/15 +10/15)*

= -(10 +19/15) = -(10 +1 4/15)

= -11 4/15

___

* you know at this point that the correct answer is B. The integer part cannot be 10, but must be 11.

Answer:

I think it's choice B and D
