Answer:

-1 13/56

Step-by-step explanation:

\frac{4}{5}  \times (  - \frac{ 3}{7} ) -  \frac{3}{8} +  \frac{6}{5} \times ( -  \frac{3}{7} ) =  \\  =  -  \frac{12}{35}   -  \frac{3}{8}  +  \frac{6}{5}  \times ( -  \frac{3}{7} ) \\  =  -  \frac{12}{35}  -  \frac{3}{8}  + ( -  \frac{18}{35} ) \\  =  -  \frac{96}{280}  -  \frac{105}{280}  -  \frac{144}{280}  \\  =  -  \frac{201}{280}  -  \frac{144}{280}  \\  =  \frac{345}{280}  = -  1 \frac{65}{280}  \\  = - 1 \frac{13}{56}
