Answer 2

$\frac{3}{4}:\frac{5}{4}\cdot \frac{5}{6}\cdot \frac{6}{7}\cdot \frac{7}{8}\cdot \frac{8}{9}\cdot \frac{9}{10}\cdot \frac{10}{11}:\frac{12}{11}=\\\\=\frac{3}{4}\cdot \frac{4}{5}\cdot \frac{5}{6}\cdot \frac{6}{7}\cdot \frac{7}{8}\cdot \frac{8}{9}\cdot \frac{9}{10}\cdot \frac{10}{11}\cdot \frac{11}{12}=\frac{3}{12}=\frac{1}{4}=0,25$
