Accepted Answer

4) $1\frac{1}{3}=\frac{4}{3}$, $8\frac{2}{3}=\frac{26}{3}$, $3\frac{3}{8}=\frac{27}{8}$, $1\frac{5}{8}=\frac{13}{8}$, $1\frac{5}{6}=\frac{11}{6}$.

$\frac{26}{3}:\frac{4}{9}=\frac{26}{3}\cdot\frac{9}{4}=\frac{39}{2}$.

$\frac{39}{2}-\frac{27}{8}+\frac{13}{8}=\frac{156-27+13}{8}=\frac{142}{8}=\frac{71}{4}$.

$\frac{4}{3}\cdot\frac{71}{4}-\frac{11}{6}=\frac{71}{3}-\frac{11}{6}=\frac{142-11}{6}=\frac{131}{6}=21\frac{5}{6}$.

Ответ: $21\frac{5}{6}$.

3) $\frac{11,8+2,7}{2,9}=\frac{14,5}{2,9}=5$.

Ответ: $5$.

6) $\frac{3,9-1,8}{0,3}=\frac{2,1}{0,3}=7$.

Ответ: $7$.

4) \(1\frac{1}{3}\cdot\left(8\frac{2}{3}:\frac{4}{9}-3\frac{3}{8}+1\frac{5}{8}\right)-1\frac{5}{6}\); 3) \(\frac{11,8+2,7}{2,9}\); 6) \(\frac{3,9-1,8}{0,3}\).
