Answer 1

Resposta: -1,3

Explicação passo a passo:

$(\frac{1}{3} + \frac{1}{6} ) - 1 + (\frac{3}{5} - 0,4) -1 =\\\\= (\frac{2+1}{6}) - 1 + (\frac{1}{5}) -1 = \\\\= \frac{3}{6} - 1 + \frac{1}{5} - 1 =\\\\= -\frac{3}{6} - \frac{4}{5} =\\\\= \frac{-15-24}{30} = \\\\= \frac{-39}{30} =\\\\= -\frac{13}{10} = -1,3$
