\(\frac{1}{2}+\frac{3}{4}+\frac{5}{6}+\frac{8}{10}\times\frac{9}{15}\div\frac{3}{5}\)
= \(\frac{12}{24}+\frac{18}{24}+\frac{20}{24}+\frac{72}{150}\div\frac{3}{5}\)
= \(\frac{30}{24}+\frac{20}{24}+\frac{72}{150}\times\frac{5}{3}\)
=\(\frac{50}{24}+\frac{24}{30}\times\frac{1}{1}\)
= \(\frac{54}{24}+\frac{24}{30}=\frac{9}{4}+\frac{4}{5}\)
= \(\frac{45}{20}+\frac{16}{20}\)
= \(\frac{61}{20}\)
