Answer 1

$- \frac{7}{8} m - 1 = - \frac{7}{8} \times ( - 1) - 1 = \frac{7}{8} - 1 = - \frac{1}{8} = - 0.125$

$- \frac{7}{8} m - 1 = - \frac{7}{8} \times \frac{4}{7} - 1 = - 0.5 - 1 = - 1.5$

$- 9 \times |x| -3 .8 = - 9 \times | - 9| - 3.8 = - 9 \times 9 - 3.8 = - 81 - 3.8 = - 84.8$

$- 9 \times |x| -3 .8 = - 9 \times | - 3.3| - 3.8 = - 9 \times 3.3 - 3.8 = - 29.7 - 3.8 = - 33.5$

$\frac{1}{2} {b}^{3} - 3 {c}^{2} = \frac{1}{2} \times ( - 2) {}^{3} - 3 \times ( - \frac{1}{3} ) {}^{2} = - \frac{8}{2} - \frac{3}{9} = - 4 - \frac{1}{3} = - 4 \frac{1}{3}$

$- 1 - \frac{5}{9} a = - 1 - \frac{5}{9} \times ( - 1) = - 1 + \frac{5}{9} = - \frac{4}{9}$

$- 1 - \frac{5}{9} a = - 1 - \frac{5}{9} \times \frac{3}{5} = - 1 - \frac{1}{3} = - 1 \frac{1}{3}$
