[tex]\frac{\frac{1}{9}}{\frac{1}{7}} =\frac{1\cdot \:7}{9\cdot \:1} =\frac{7}{9}[/tex]
[tex]\frac{7}{\frac{7}{3}} =\frac{7\cdot \:3}{7} =3[/tex]
[tex]\frac{\frac{5}{8}}{\frac{2}{3}} =\frac{5\cdot \:3}{8\cdot \:2}=\frac{15}{8\cdot \:2} =\frac{15}{16}[/tex]
[tex]\frac{\frac{7}{9}}{\frac{1}{3}} =\frac{7\cdot \:3}{9\cdot \:1} =\frac{7\cdot \:3}{9} =\frac{7\cdot \:3}{3\cdot \:3} =\frac{7}{3}[/tex]
[tex]\frac{\frac{5}{8}}{\frac{1}{2}} =\frac{5\cdot \:2}{8\cdot \:1} =\frac{5\cdot \:2}{8} =\frac{5\cdot \:2}{2\cdot \:4} =\frac{5}{4}[/tex]
