$\frac{7}{9} = \frac{28}{36}$
$\frac{11}{12} = \frac{33}{36}$
$\frac{28}{36} < \frac{33}{36}$
$\frac{7}{9} < \frac{11}{12}$
$\frac{9}{10} = \frac{27}{30}$
$\frac{23}{30} = \frac{23}{30}$
$\frac{27}{30} > \frac{23}{30}$
$\frac{9}{10} > \frac{23}{30}$
$\frac{5}{8} = \frac{35}{56}$
$\frac{6}{7} = \frac{48}{56}$
$\frac{35}{56} < \frac{48}{56}$
$\frac{5}{8} < \frac{6}{7}$
$\frac{3}{4} = \frac{27}{36}$
$\frac{7}{18} = \frac{14}{36}$
$\frac{27}{36} > \frac{14}{36}$
$\frac{3}{4} > \frac{7}{18}$
$8 ÷ 15 = \frac{8}{15}$
$4 ÷ 9 = \frac{4}{9}$ 
 $\frac{8}{15} > \frac{4}{9}$
$3 ÷ 8 = \frac{3}{8}$ 
$5 ÷ 16 = \frac{5}{16}$ 
$\frac{3}{8} > \frac{5}{16}$
$7 ÷ 12 = \frac{7}{12}$
$3 ÷ 10 = \frac{3}{10}$
$\frac{7}{12} > \frac{3}{10}$
$11 ÷ 18 = \frac{11}{18}$
$5 ÷ 8 = \frac{5}{8}$
$\frac{11}{18} < \frac{5}{8}$
$\frac{3}{56} > \frac{1}{19} > \frac{1}{20}$
$8\div100=\frac{2}{25}$(升)
$5\div35=\frac{1}{7}$(升)
$\frac{2}{25}=\frac{14}{175},$
$\frac{1}{7}=\frac{25}{175}$
因为$\frac{25}{175}>\frac{14}{175},$
所以$\frac{1}{7}>\frac{2}{25}$
答:不相等,乙车耗油量更多。
$\frac{18}{25} = \frac{72}{100},$
$\frac{13}{20} = \frac{65}{100},$
$\frac{4}{5} = \frac{80}{100},$
因为$\frac{65}{100} < \frac{72}{100} < \frac{80}{100},$所以$\frac{13}{20} < \frac{18}{25} < \frac{4}{5},$
答:小兵家剩下的麦子最多,小丽家剩下的麦子最少。
