Accepted Answer

$\frac{7}{48}:6\frac{6}{7}=\frac{7}{48}:\frac{48}{7}=\frac{7}{48}\cdot\frac{7}{48}=\frac{49}{2304}$.
$6\frac{7}{35}:\frac{4}{39}=\frac{31}{5}\cdot\frac{39}{4}=\frac{1209}{20}=60\frac{9}{20}$.
$10\frac{3}{5}:1\frac{23}{30}=\frac{53}{5}:\frac{53}{30}=\frac{53}{5}\cdot\frac{30}{53}=6$.
$1\frac{7}{25}:2\frac{6}{25}=\frac{32}{25}:\frac{56}{25}=\frac{32}{25}\cdot\frac{25}{56}=\frac{4}{7}$.
$3\frac{5}{9}:1=3\frac{5}{9}$.
$15:6\frac{1}{4}=15:\frac{25}{4}=15\cdot\frac{4}{25}=\frac{12}{5}=2\frac{2}{5}$.
$4\frac{1}{5}:7=\frac{21}{5}:7=\frac{21}{5}\cdot\frac{1}{7}=\frac{3}{5}$.
$1\frac{7}{9}:3\frac{3}{7}=\frac{16}{9}:\frac{24}{7}=\frac{16}{9}\cdot\frac{7}{24}=\frac{14}{27}$.
$43\frac{10}{29}:5=\frac{1257}{29}:5=\frac{1257}{145}=8\frac{97}{145}$.
$34\frac{17}{42}:14=\frac{1445}{42}:14=\frac{1445}{588}=2\frac{269}{588}$.

Ответ: 1) $\frac{49}{2304}$; 2) $60\frac{9}{20}$; 3) $6$; 4) $\frac{4}{7}$; 5) $3\frac{5}{9}$; 6) $2\frac{2}{5}$; 7) $\frac{3}{5}$; 8) $\frac{14}{27}$; 9) $8\frac{97}{145}$; 10) $2\frac{269}{588}$.
