a) $$\frac{7}{9}: \frac{7}{18}$$ = $$\frac{7}{9} \cdot \frac{18}{7}$$ = $$\frac{126}{63}$$ = 2
б) $$\frac{3}{4}: \frac{1}{3}$$ = $$\frac{3}{4} \cdot \frac{3}{1}$$ = $$\frac{9}{4}$$ = 2$$\frac{1}{4}$$
д) $$\frac{6}{11}: \frac{6}{11}$$ = $$\frac{6}{11} \cdot \frac{11}{6}$$ = 1
ж) $$\frac{5}{7}: \frac{1}{7}$$ = $$\frac{5}{7} \cdot \frac{7}{1}$$ = 5
и) $$\frac{3}{14}: \frac{1}{7}$$ = $$\frac{3}{14} \cdot \frac{7}{1}$$ = $$\frac{21}{14}$$ = 1$$\frac{7}{14}$$ = 1$$\frac{1}{2}$$
г) $$\frac{9}{13}: \frac{3}{13}$$ = $$\frac{9}{13} \cdot \frac{13}{3}$$ = 3
e) $$\frac{15}{22}: \frac{5}{22}$$ = $$\frac{15}{22} \cdot \frac{22}{5}$$ = 3
