2) $12 : \frac{6}{7} =$
3) $15 : \frac{10}{11} =$
4) $1 : \frac{16}{17} =$
5) $\frac{7}{13} : 4 = \frac{7}{13} * \frac{1}{4} =$
6) $\frac{12}{19} : 3 =$
7) $4\frac{1}{6} : \frac{5}{9} = \frac{25}{6} : \frac{5}{9} =$
8) $\frac{9}{16} : 1\frac{1}{2} =$
9) $1\frac{5}{7} : 3\frac{3}{4} = \frac{12}{7} : \frac{15}{4} =$
10) $5\frac{1}{2} : 3\frac{2}{3} =$
$9 : \frac{4}{5} = 9 * \frac{5}{4} = \frac{45}{4} = 11\frac{1}{4}$
$12 : \frac{6}{7} = 12 * \frac{7}{6} = 2 * \frac{7}{1} = 14$
$15 : \frac{10}{11} = 15 * \frac{11}{10} = 3 * \frac{11}{2} = \frac{33}{2} = 16\frac{1}{2}$
$1 : \frac{16}{17} = 1 * \frac{17}{16} = 1\frac{1}{16}$
$\frac{7}{13} : 4 = \frac{7}{13} * \frac{1}{4} = \frac{7}{52}$
$\frac{12}{19} : 3 = \frac{12}{19} * \frac{1}{3} = \frac{4}{19} * \frac{1}{1} = \frac{4}{19}$
$4\frac{1}{6} : \frac{5}{9} = \frac{25}{6} : \frac{5}{9} = \frac{25}{6} * \frac{9}{5} = \frac{5}{2} * \frac{3}{1} = \frac{15}{2} = 7\frac{1}{2}$
$\frac{9}{16} : 1\frac{1}{2} = \frac{9}{16} : \frac{3}{2} = \frac{9}{16} * \frac{2}{3} = \frac{3}{8} * \frac{1}{1} = \frac{3}{8}$
$1\frac{5}{7} : 3\frac{3}{4} = \frac{12}{7} : \frac{15}{4} = \frac{12}{7} * \frac{4}{15} = \frac{4}{7} * \frac{4}{5} = \frac{16}{35}$
$5\frac{1}{2} : 3\frac{2}{3} = \frac{11}{2} : \frac{11}{3} = \frac{11}{2} * \frac{3}{11} = \frac{1}{2} * \frac{3}{1} = \frac{3}{2} = 1\frac{1}{2}$
