\[\frac{5}{6} \cdot 90 = \frac{5 \cdot 90}{6} = \frac{450}{6} = 75\]
\[\frac{7}{8} \cdot 240 = \frac{7 \cdot 240}{8} = \frac{1680}{8} = 210\]
\[\frac{9}{7} \cdot 56 = \frac{9 \cdot 56}{7} = \frac{504}{7} = 72\]
\[\frac{17}{12} \cdot 84 = \frac{17 \cdot 84}{12} = \frac{1428}{12} = 119\]
\[\frac{14}{100} \cdot 4000 = \frac{14 \cdot 4000}{100} = \frac{56000}{100} = 560\]
\[\frac{134}{100} \cdot 800 = \frac{134 \cdot 800}{100} = \frac{107200}{100} = 1072\]
