[tex] \frac{5}{2} \div \frac{5}{7} = \frac{5}{2} \times \frac{7}{5} = \frac{7}{2} [/tex]
[tex] \frac{6}{10} \div \frac{11}{5} = \frac{6}{10} \times \frac{5}{11} = \frac{3}{11} [/tex]
[tex] \frac{4}{9} \div \frac{7}{3} = \frac{4}{9} \times \frac{3 }{7} = \frac{4}{21} [/tex]
[tex] \frac{8}{15} \div \frac{11}{12} = \frac{8}{15} \times \frac{12}{11} = \frac{32}{55} [/tex]
[tex] \frac{5}{11} \div \frac{13}{5} = \frac{5}{11} \times \frac{5}{13} = \frac{25}{143} [/tex]
