Ответ:

а) \(\frac{2}{3}:\frac{13}{24}=\frac{2}{3}\cdot\frac{24}{13}=\frac{16}{13}=1\frac{3}{13}\).

б) \(\frac{15}{16}:\frac{3}{10}=\frac{15}{16}\cdot\frac{10}{3}=\frac{25}{8}=3\frac{1}{8}\).

в) \(\frac{36}{49}:\frac{6}{7}=\frac{36}{49}\cdot\frac{7}{6}=\frac{6}{7}\).

г) \(\frac{3}{10}:\frac{7}{100}=\frac{3}{10}\cdot\frac{100}{7}=\frac{30}{7}=4\frac{2}{7}\).

Ответ: а) \(1\frac{3}{13}\); б) \(3\frac{1}{8}\); в) \(\frac{6}{7}\); г) \(4\frac{2}{7}\).
