[tex]\frac{\frac{4}{5}}{\frac{1}{2}-\frac{1}{5}} - \frac{2}{3}-(\frac{3}{8}-1\frac{1}{3})=\frac{\frac{4}{5}}{\frac{5}{10}-\frac{2}{10}}-\frac{2}{3}-(\frac{9}{24}-\frac{32}{24})=\frac{\frac{4}{5}}{\frac{3}{10}}-\frac{2}{3}-(-\frac{23}{24})=\frac{4}{5}*\frac{10}{3}-\frac{16}{24}+\frac{23}{24}=\frac{8}{3}+\frac{7}{24}=\frac{64}{24}+\frac{7}{24}=\frac{71}{24}=2\frac{23}{24}[/tex]
