Answer 1

-1,5 = $\frac{-15}{10}$

$0,444=\frac{4}{9}$

$(\frac{-15}{10} -\frac{4}{9} ) (\frac{-9}{4} ) +( \frac{-3}{7}) =\\= (\frac{-135-40}{90} ) (\frac{-9}{4} ) + (\frac{-3}{7} ) =\\= \frac{-175}{90} ) (\frac{-9}{4} ) + (\frac{-3}{7} ) =\\= \frac{175}{40} - \frac{3}{7} =\\= \frac{35}{8} - \frac{3}{7} =\\= \frac{245-24}{56} = \frac{221}{56}$
