$\frac{31}{20} ; \frac{33}{10} ; \frac{37}{20} \frac{39}{20}$

$\frac{22}{13} ; \frac{22}{15} ; \frac{22}{17} ; \frac{22}{19}$

$\frac{23}{34} ; \frac{25}{54} ; \frac{27}{74} ; \frac{29}{94}$

$\frac{1}{71} ; \frac{3}{73} ; \frac{9}{79}$

$\frac{231}{342} = \frac{77}{114}$

$\frac{234}{342} = \frac{78}{114} = \frac{39}{57} = \frac{13}{19}$

$\frac{237}{342} = \frac{79}{114}$

$\frac{231}{345} = \frac{77}{115}$

$\frac{234}{345} = \frac{78}{115}$

$\frac{237}{345} = \frac{79}{115}$

$\frac{231}{348} = \frac{77}{116}$

$\frac{234}{348} = \frac{78}{116} = \frac{39}{58}$

$\frac{237}{348} = \frac{79}{116}$
