Answer 2

Answer:

$\frac{2}{5} *(-\frac{1}{9} ) + \frac{2}{5} * (-\frac{3}{7})$ $=-\frac{68}{315}$

Step-by-step explanation:

$\frac{2}{5} *(-\frac{1}{9} ) + \frac{2}{5} * (-\frac{3}{7})$

$=-\frac{2}{5} *(\frac{1}{9} + \frac{3}{7})$

$=-\frac{2}{5} *(\frac{7 + 27}{63} )$

$=-\frac{2}{5} *(\frac{34}{63} )$

$=-\frac{68}{315}$
