1) $1:\frac{13}{14}=\frac{14}{14} :\frac{13}{14} =\frac{14}{14} *\frac{14}{13}=\frac{14}{13} =1\frac{1}{13}$

2)$1:\frac{15}{17}=1*\frac{17}{15}=1\frac{2}{15}$

3)$1:\frac{9}{14} =1*\frac{14}{9}=1\frac{5}{9}$

4) $1:\frac{17}{21} =1*\frac{21}{17}=1\frac{4}{17}$

5)$2:\frac{4}{7} =\frac{2*7}{4} =\frac{7}{2} =3\frac{1}{2}$

6)$3:\frac{15}{16} =\frac{3*16}{15} =\frac{16}{5} =3\frac{1}{5}$

7)$7:\frac{14}{15} =\frac{7*15}{14} =\frac{15}{2} =7\frac{1}{2}$

8)$6:\frac{18}{23} =\frac{6*23}{18}=\frac{23}{3} =7\frac{2}{3}$

9)$3:\frac{6}{7}=\frac{3*7}{6}=\frac{7}{2} =3\frac{1}{2}$

10)$2:\frac{7}{8}=\frac{2*8}{7}=\frac{16}{7}=2\frac{2}{7}$

11)$4:\frac{10}{11}=\frac{4*11}{10}=\frac{2*11}{5} =\frac{22}{5}=4\frac{2}{5}$

12) $14:\frac{21}{22}=\frac{14*22}{21} =\frac{2*22}{3} =\frac{44}{3} =14\frac{2}{3}$

1)$1:\frac{7}{9}=\frac{9}{7}=1\frac{2}{7}$

2)$1:\frac{7}{15}=\frac{15}{7}=2\frac{1}{7}$

3)$2:\frac{8}{11} =\frac{2*11}{8} =\frac{11}{4}=2\frac{3}{4}$

4)$8:\frac{24}{25} =\frac{8*25}{24} =\frac{25}{3} =8\frac{1}{3}$

1) $1:x=\frac{3}{4}\\x=1:\frac{3}{4}\\x=\frac{4}{3}=1\frac{1}{3}$

2)$2:x=\frac{8}{11}\\x=2:\frac{8}{11}\\x=\frac{2*11}{8}=\frac{11}{4}=2\frac{3}{4}$

3)$3:x=\frac{15}{17}\\x=3:\frac{15}{17}\\x=\frac{3*17}{15} =\frac{17}{5}=3\frac{2}{5}$
