Ответ:

1)

\(10\frac{2}{3}=\frac{32}{3},\quad 5\frac{1}{3}=\frac{16}{3},\quad 3\frac{1}{3}=\frac{10}{3}\).

\(\frac{16}{3}:\frac{10}{3}=\frac{16}{3}\cdot\frac{3}{10}=\frac{8}{5}\).

\(\frac{32}{3}-\frac{8}{5}=\frac{160-24}{15}=\frac{136}{15}=9\frac{1}{15}\).

2)

\((3,38-2,24):1,25=1,14:1,25=0,912\).

Ответ: 1) \(9\frac{1}{15}\); 2) \(0,912\).
