- Solución:

$\frac{3}{4}+\frac{5}{6}.\frac{3}{5}:\frac{1}{2}-\frac{2}{7}.\frac{7}{5}=\\\\\frac{3}{4}+\frac{5.3}{6.5}:\frac{1}{2}-\frac{2.7}{7.5}=\\\\\frac{3}{4}+\frac{15}{30}:\frac{1}{2}-\frac{14}{35}=\\\\\frac{3}{4}+\frac{15.2}{30.1}-\frac{14}{35}=\\\\\frac{3}{4}+\frac{30}{30}-\frac{14}{35}=\\\\\frac{420:4.3+420:30.30-420:35.14}{420}=\\\\\frac{315+420-168}{420}=\\\\\frac{567}{420}=\frac{189}{140}$
