Answer 1

$( - 3 frac{1}{3} times 1.9 + 19.5 div 4 frac{1}{3} ) div (0.16 - frac{62}{75} ) = 2 frac{3}{4} = 2.75 \ \ 1) : : - 3 frac{1}{3} times 1.9 = - frac{10}{3} times frac{19}{10} = - frac{19}{3} = - 6 frac{1}{3} \ \ 2) : : 19.5 div 4 frac{1}{3} = frac{195}{10} times frac{3}{13} = frac{15 times 3}{10} = frac{9}{2} =4 frac{1}{2} \ \ 3) : : - 6 frac{1}{3} + 4 frac{1}{2} = - 2 frac{ - 2 + 3}{6} = - 1 frac{5}{6} \ \ 4) : : 0.16 - frac{62}{75} = frac{4}{25} - frac{62}{75} = frac{12 - 62}{75} = - frac{50}{75} = - frac{2}{3} \ \ 5) : : - 1 frac{5}{6} div ( - frac{2}{3} ) = frac{11 times 3}{6 times 2} = frac{11}{4} = 2 frac{3}{4} = 2.75$
