Accepted Answer

$4\frac{1}{2}:2\frac{1}{4}=\frac{9}{2}:\frac{9}{4}=\frac{9}{2}\cdot\frac{4}{9}=2$.
$6\frac{2}{3}:1\frac{7}{9}=\frac{20}{3}:\frac{16}{9}=\frac{20}{3}\cdot\frac{9}{16}=\frac{15}{4}=3\frac{3}{4}$.
$8\frac{5}{6}:2\frac{7}{12}=\frac{53}{6}:\frac{31}{12}=\frac{53}{6}\cdot\frac{12}{31}=\frac{106}{31}=3\frac{13}{31}$.
$5\frac{3}{7}:1\frac{5}{14}=\frac{38}{7}:\frac{19}{14}=\frac{38}{7}\cdot\frac{14}{19}=4$.
$9\frac{4}{5}:3\frac{1}{10}=\frac{49}{5}:\frac{31}{10}=\frac{49}{5}\cdot\frac{10}{31}=\frac{98}{31}=3\frac{5}{31}$.
$11\frac{1}{4}:2\frac{1}{2}=\frac{45}{4}:\frac{5}{2}=\frac{45}{4}\cdot\frac{2}{5}=\frac{9}{2}=4\frac{1}{2}$.

Ответ: 1) $2$; 2) $3\frac{3}{4}$; 3) $3\frac{13}{31}$; 4) $4$; 5) $3\frac{5}{31}$; 6) $4\frac{1}{2}$.
