$\frac{\frac{7}{10}+\frac{1}{2}}{\frac{4}{5}+\frac{3}{4}}$ $=(\frac{7}{10}+\frac{1}{2})\div(\frac{4}{5}+\frac{3}{4})$ $=(\frac{7}{10}+\frac{5}{10})\div(\frac{16}{20}+\frac{15}{20})$ $=\frac{12}{10}\div\frac{31}{20}$ $=\frac{6}{5}\div\frac{31}{20}$ $=\frac{6}{5}\times\frac{20}{31}$ $=\frac{6}{1}\times\frac{4}{31}$ $=\frac{24}{31}$
