Сравним дроби \(\frac{2}{13}\) и \(\frac{15}{16}\). \(\frac{2}{13} \approx 0.15\) \(\frac{15}{16} \approx 0.94\) \(0.15 < 0.94\), значит, \(\frac{2}{13} < \frac{15}{16}\) Сравним дроби \(\frac{7}{22}\) и \(\frac{51}{64}\). \(\frac{7}{22} \approx 0.32\) \(\frac{51}{64} \approx 0.80\) \(0.32 < 0.80\), значит, \(\frac{7}{22} < \frac{51}{64}\) Сравним дроби \(\frac{51}{100}\) и \(\frac{54}{110}\). \(\frac{51}{100} = 0.51\) \(\frac{54}{110} \approx 0.49\) \(0.51 > 0.49\), значит, \(\frac{51}{100} > \frac{54}{110}\) Сравним дроби \(\frac{3}{4}\) и \(\frac{62}{125}\). \(\frac{3}{4} = 0.75\) \(\frac{62}{125} = 0.496\) \(0.75 > 0.496\), значит, \(\frac{3}{4} > \frac{62}{125}\)

Ответ: \(\frac{2}{13} < \frac{15}{16}\); \(\frac{7}{22} < \frac{51}{64}\); \(\frac{51}{100} > \frac{54}{110}\); \(\frac{3}{4} > \frac{62}{125}\)
