Answer 1

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