Answer 1

Ответ:

$a = ( - 3 \frac{4}{5} + 4 \frac{3}{10} ) \div ( - 1 \frac{1}{3} ) \\ a = \frac{ - 19 \times 2 + 43}{10} \times \frac{ - 3}{4} \\ a = - \frac{5}{10} \times \frac{3}{4} = - \frac{3}{8} \\ |a| = \frac{3}{8}$

$b = (5 \frac{7}{8} - 6 \frac{1}{2} ) \div 3 \frac{1}{8} \\ b = \frac{47 - 13 \times 4}{8} \times \frac{8}{25} \\ b = - \frac{5}{8} \times \frac{8}{25} = - \frac{1}{5} \\ |b| = \frac{1}{5}$

$c = (2 \frac{1}{6} - 5 \frac{3}{8} ) \div ( - 1 \frac{7}{48} ) \\ c = \frac{13 \times 4 - 43 \times 3}{24} \times ( - \frac{48}{55} ) \\ c = \frac{77}{24} \times \frac{48}{55} = \frac{7 \times 2}{5} = 2 \frac{4}{5} \\ |c| = c$

$d = ( - 5 \frac{5}{27} + 4 \frac{5}{18} ) \div ( - 2 \frac{2}{27} ) \\ d = \frac{ - 140 \times 2 + 77 \times 3}{54} \times ( - \frac{27}{56} ) \\ d = \frac{49}{54} \times \frac{27}{56} = \frac{7}{2 \times 8} = \frac{7}{16} \\ |d| = d$
