a) \(\frac{{12}}{{14}}:\frac{4}{3}\)

= \(\frac{{12}}{{14}} \times \frac{3}{4}\) = \(\frac{9}{{14}}\)

b) \(\frac{{18}}{{22}}:\frac{6}{5}\)

= \(\frac{{18}}{{22}} \times \frac{5}{6}\) = \(\frac{{15}}{{22}}\)

c) \(\frac{5}{3}:\frac{{10}}{7}\)

= \(\frac{5}{3} \times \frac{7}{{10}}\) = \(\frac{7}{6}\)

d) \(\frac{{14}}{{20}}:\frac{7}{4}\)

= \(\frac{{14}}{{20}} \times \frac{4}{7}\) = \(\frac{2}{5}\)
