First work out the bracket: -1 2/3, make this into one fraction 
                                          a b/c = (ac+b)/c 
                                          ignore the negative for now, so 3+2= 5 so your                                             fraction is -5/3
Then multiply: 3/5 x -5/3 = -15/15 so your answer is -1
-1 2/3 = - (1*3+2/3)
          = - (3+2/3)
          = -5/3

Now lets multiply
= 3/5 * -5/3
= 3*-5 / 5*15
= -15/15
= -1
