\(\frac{0,8\div\left(\frac{4}{5}\cdot1,25\right)}{0,64-\frac{1}{25}}+\left(1,2\cdot0,5\right)\div\frac{3}{5}\)

\(=\frac{0,8\div\left(0,8\cdot1,25\right)}{0,64-0,04}+\left(1,2\cdot0,5\right)\div0,6\)

\(=\frac{0,8\div1}{0,6}+0,6\div0,6\)

\(=\frac{0,8}{0,6}+1\)

\(=\frac{4}{3}+1=\frac{7}{3}\)

\(\frac{0,8\div\left(\frac{4}{5}\cdot1,25\right)}{0,64-\frac{1}{25}}+\left(1,2\cdot0,5\right)\div\frac{3}{5}\)

\(=\frac{0,8\div\left(0,8.1,25\right)}{0,64-0,04}+\left(1,2.0,5\right)\div0,6\)

\(=\frac{0,8\div1}{0,6}+0,6\div0,6\)

\(=\frac{4}{3}+1\)

\(=\frac{7}{3}\)

Ta có: \(\frac{0,8:\left(\frac{4}{5}\cdot1,25\right)}{0,64-\frac{1}{25}}+\frac{\left(1,08-\frac{2}{25}\right):\frac{4}{7}}{\left(6\frac{5}{9}-3\frac{1}{4}\right)\cdot2\frac{2}{17}}+\frac{\left(1,2\cdot0,5\right)}{\frac{4}{5}}\)

\(=\frac{\frac{4}{5}:\left(\frac{4}{5}\cdot\frac{5}{4}\right)}{\frac{16}{25}-\frac{1}{25}}+\frac{\left(\frac{27}{25}-\frac{2}{25}\right)\cdot\frac{7}{4}}{\left(\frac{59}{9}-\frac{13}{4}\right)\cdot\frac{36}{17}}+\frac{6}{5}\cdot\frac{1}{2}\cdot\frac{5}{4}\)

\(=\frac{\frac{4}{5}}{\frac{3}{5}}+\frac{\frac{7}{4}}{\frac{119}{36}\cdot\frac{36}{17}}+\frac{3}{4}\)

\(=\frac{4}{5}\cdot\frac{5}{3}+\frac{7}{4}\cdot\frac{1}{7}+\frac{3}{4}=\frac{4}{3}+\frac{1}{4}+\frac{3}{4}=\frac{7}{3}\)
