Давайте решим примеры и найдем соответствующие значения:
1. \(\frac{14}{21} - \frac{6}{14}\) = \(\frac{2}{3} - \frac{3}{7}\) = \(\frac{14}{21} - \frac{9}{21}\) = \(\frac{5}{21}\)
2. \(\frac{33}{42} - \frac{11}{24}\) = \(\frac{11}{14} - \frac{11}{24}\) = \(\frac{132}{168} - \frac{77}{168}\) = \(\frac{55}{168}\)
3. \(\frac{14}{45} - \frac{19}{25} + \frac{13}{45} + \frac{6}{25}\) = \(\frac{14}{45} + \frac{13}{45} - \frac{19}{25} + \frac{6}{25}\) = \(\frac{27}{45} - \frac{13}{25}\) = \(\frac{3}{5} - \frac{13}{25}\) = \(\frac{15}{25} - \frac{13}{25}\) = \(\frac{2}{25}\)
Теперь сопоставим ответы:
* \(\frac{14}{21} - \frac{6}{14}\) = \(\frac{5}{21}\)
* \(\frac{33}{42} - \frac{11}{24}\) = \(\frac{55}{168}\)
* \(\frac{14}{45} - \frac{19}{25} + \frac{13}{45} + \frac{6}{25}\) = \(\frac{2}{25}\)
