\(1\frac{5}{3}-\frac{3}{5}:0,75\cdot1\frac{1}{4}+\frac{1}{5}\)
\(=2\frac{2}{3}-\frac{3}{5}\cdot\frac{4}{3}\cdot1\frac{1}{4}+\frac{1}{5}\)
\(=2\frac{2}{3}-\frac{4}{5}\cdot\frac{5}{4}+\frac{1}{5}\)
\(=2\frac{2}{3}-1+\frac{1}{5}\)
\(=1\frac{2}{3}+\frac{1}{5}\)
\(=\frac{5}{3}+\frac{1}{5}\)
\(=1\frac{13}{15}\)
