Ты просишь меня решить примеры с дробями.

Привет! Давай решим эти примеры вместе. 509. a) $-\frac{3}{5} - \frac{9}{10} = -\frac{6}{10} - \frac{9}{10} = -\frac{15}{10} = -1\frac{5}{10} = -1\frac{1}{2}$ б) $-\frac{15}{24} - \frac{3}{8} = -\frac{15}{24} - \frac{9}{24} = -\frac{24}{24} = -1$ в) $-\frac{2}{3} - \frac{5}{6} = -\frac{4}{6} - \frac{5}{6} = -\frac{9}{6} = -1\frac{3}{6} = -1\frac{1}{2}$ г) $-\frac{7}{6} - \frac{5}{24} = -\frac{28}{24} - \frac{5}{24} = -\frac{33}{24} = -1\frac{9}{24} = -1\frac{3}{8}$ д) $\frac{2}{5} - \frac{13}{50} = \frac{20}{50} - \frac{13}{50} = \frac{7}{50}$ е) $-\frac{50}{160} - \frac{9}{16} = -\frac{50}{160} - \frac{90}{160} = -\frac{140}{160} = -\frac{7}{8}$ 510. a) $-\frac{1}{6} + \frac{1}{9} = -\frac{3}{18} + \frac{2}{18} = -\frac{1}{18}$ б) $\frac{3}{10} - \frac{2}{15} = \frac{9}{30} - \frac{4}{30} = \frac{5}{30} = \frac{1}{6}$ в) $-\frac{2}{10} - \frac{6}{15} = -\frac{1}{5} - \frac{2}{5} = -\frac{3}{5}$ г) $\frac{3}{8} - \frac{2}{9} = \frac{27}{72} - \frac{16}{72} = \frac{11}{72}$ д) $-\frac{5}{12} + \frac{4}{15} = -\frac{25}{60} + \frac{16}{60} = -\frac{9}{60} = -\frac{3}{20}$ е) $\frac{2}{16} - \frac{3}{39} = \frac{1}{8} - \frac{1}{13} = \frac{13}{104} - \frac{8}{104} = \frac{5}{104}$
