Answer 1

$6m - 2(m + \frac{3}{10} ) + 4(m - \frac{1}{20} ) = 6m - 2m - \frac{6}{10} + 4m - \frac{4}{20} = 8m - 0.6 - 0.2 = 8m - 0.8 = 0.8(10m - 1)$

$1.2(4 - 3a) + 0.4a - 5.8 = 4.8 - 3.6a + 0.4a - 5.8 = - 1 - 3.2a = - 1 - 3.2 \times ( - \frac{5}{32}) = - 1 + \frac{3.2 \times 5}{32} = \frac{32 \times 5}{32 \times 10} - 1 = \frac{1}{2} - 1 = - 0.5$
