Answer 1

$- \frac{5}{9} (5.4p - 1 \frac{4}{5} m) - 6.4( - \frac{3}{8} p + 2.5m) = - \frac{5 \times 54}{9 \times 10} p + \frac{5 \times 9}{9 \times 5} m + \frac{64 \times 3}{10 \times 8} p - 6.4 \times 2.5m = - 3p + m + 2.4p - 16m = - 0.6p - 15m = - 0.6 \times ( - 10) - 15 \times 0.1 = 6 - 1.5 = 4.5$
