Answer:

$\frac{23}{28}$ · $\frac{13}{28}$ = $\frac{299}{28}$ = 10$\frac{19}{28}$

$\frac{11}{20}$ : $\frac{2}{4}$ = $\frac{11}{20}$ : $\frac{10}{20}$ = $\frac{20}{11}$ · $\frac{20}{10}$ = $\frac{400}{110}$ = $\frac{200}{55}$ = 3$\frac{35}{55}$

$\frac{15}{17}$ : $\frac{9}{17}$ = $\frac{17}{15}$ · $\frac{17}{9}$ = $\frac{51}{45}$ · $\frac{85}{45}$ = $\frac{4335}{45}$ = 96$\frac{15}{45}$

$\frac{5}{6}$ · $\frac{25}{30}$ = $\frac{5}{6}$ · $\frac{5}{6}$ = $\frac{25}{6}$ = 4$\frac{1}{6}$
