解答ステップ

(\frac{6}{7}) - (\frac{11}{14}) + (- \frac{9}{14}) - (- \frac{4}{7})

(\frac{6}{7}) - (\frac{11}{14}) + (- \frac{9}{14}) - (- \frac{4}{7}) = \frac{6}{7} - \frac{11}{14} - \frac{9}{14} + \frac{4}{7}

= \frac{6}{7} - \frac{11}{14} - \frac{9}{14} + \frac{4}{7}

\frac{6}{7} - \frac{11}{14} - \frac{9}{14} + \frac{4}{7} = 0

= 0
