Answer 1

9514 1404 393

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.
