Answer 1

Ответ:

Пошаговое объяснение:

$1) -\frac{4}{5}$

$2) -\frac{3}{3} = -1$

$3) - \frac{1}{4} - \frac{5}{7} = - \frac{27}{28}$

$4) -\frac{5}{6} -\frac{1}{3} = -\frac{7}{6} = - 1\frac{1}{6}$

$5) -4\frac{3}{8} -2\frac{1}{4} = - \frac{35}{8} - \frac{9}{4} = - \frac{35}{8} - \frac{18}{8} = -\frac{53}{8} = -6\frac{5}{8}$

$6) -6\frac{1}{2} - 3\frac{5}{7} = -\frac{13}{2} - \frac{26}{7} = -\frac{91}{14} - \frac{52}{14} = -\frac{143}{14} = -10\frac{3}{14}$

$7) - \frac{7}{7} = -1$

$8) -\frac{1}{8} -\frac{3}{4} = -\frac{1}{8} -\frac{6}{8} = -\frac{7}{8}$
