Answer 1

$\displaystyle 1)\frac{5}{9}:\frac{2}{9}=\frac{5}{9}*\frac{9}{2}=5*\frac{1}{2}=\frac{5}{2}=2\frac{1}{2}\\\\ 2)\frac{13}{15}:\frac{7}{25}=\frac{13}{15}*\frac{25}{7}=\frac{13}{3}*\frac{5}{7}=\frac{65}{21}=3\frac{2}{21}\\\\ 3)\frac{13}{14}:\frac{39}{112}=\frac{13}{14}*\frac{112}{39}=\frac{8}{3}=2\frac{2}{3}\\\\ 4)\frac{39}{17}:\frac{78}{153}=\frac{39}{17}*\frac{153}{78}=\frac{9}{2}=4\frac{1}{2}$
