On solving 

 (5i)\left ( -\frac{3}{5} i\right )  
we will get

(5i)\left ( -\frac{3}{5} i\right ) = 5 \times (-\frac{3}{5})\times i \times i
                           = - 3 \times i^2                                    (\because i^2 = -1)
                           = - 3 \times -1
                            = 3    

Now, in the form of   a+ib   we can write it as
  = 3+0i
