Ответ:
\(10\frac{2}{3}=\frac{32}{3}\), \(2\frac{1}{2}=\frac{5}{2}\).
\(\frac{32}{3}\cdot0,6+7:\frac{5}{2}-8,6:1,5\)
\(=\frac{32}{3}\cdot\frac{3}{5}+7\cdot\frac{2}{5}-\frac{86}{10}:\frac{15}{10}\)
\(=\frac{32}{5}+\frac{14}{5}-\frac{86}{15}=\frac{46}{5}-\frac{86}{15}=\frac{138-86}{15}=\frac{52}{15}=3\frac{7}{15}\).
Ҷавоб: \(3\frac{7}{15}\).
