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

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

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

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

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