- \(\frac{14}{9}:\frac{3}{10}=\frac{14}{9}\cdot\frac{10}{3}=\frac{140}{27}=5\frac{5}{27}\).
- \(\frac{3}{4}:\frac{1}{2}=\frac{3}{4}\cdot2=\frac{3}{2}=1\frac{1}{2}\).
- \(\frac{1}{2}:\frac{3}{5}=\frac{1}{2}\cdot\frac{5}{3}=\frac{5}{6}\).
- \(\frac{2}{7}:\frac{10}{9}=\frac{2}{7}\cdot\frac{9}{10}=\frac{9}{35}\).
- \(\frac{6}{7}:\frac{6}{5}=\frac{6}{7}\cdot\frac{5}{6}=\frac{5}{7}\).
- \(\frac{8}{15}:\frac{4}{5}=\frac{8}{15}\cdot\frac{5}{4}=\frac{2}{3}\).
