$(0.78 - 5.356 \div 5.2) \times 1.6 - 0.6 \\ 1) \frac{5.356}{5.2} = 1.03 \\ 2)0.78 - 1.03 = - (1.03 - 0.78) = - 0.25 \\ 3) - 0.25 \times 1.6 = - 0.4 \\ 4) - 0.4 - 0.6 = - 1$

$(1.47 \div 1.4 - 1.5) \times ( - \frac{5}{9} ) \div ( - 0.15) = \\ - (0.45 \times \frac{5}{9} \times \frac{100}{15} ) = - \frac{15}{9} = - \frac{5}{3}$

$\frac{4}{9} \times {( - \frac{3}{2}) }^{3} + 4.2 \div 4 = \\ - \frac{4}{9} \times \frac{27}{8} + 1.05 = - 1.5 + 1.05 = - 0.45$

$- \frac{7}{16} + \frac{3}{16} \div (4.79 - 3.15 \times 1.6) = \\- \frac{7}{16} + \frac{3}{16} \div (4.79 - 5.04) = \\- \frac{7}{16} + \frac{3}{16} \div ( - \frac{1}{4} ) = \\ - \frac{7}{16} - \frac{3}{4} = - ( \frac{7}{16} + \frac{12}{16} ) = - \frac{19}{16}$

$- 0.81 \times (\frac{ - 5}{9}) \div (1.53 \div 1.5 - 1.2) = \\ - 0.81 \times (\frac{ - 5}{9}) \div ( - 0.18) = \\ - ( \frac{9}{2} \times \frac{5}{9} ) = - \frac{5}{2}$
