$\frac{5}{12}= \frac{5\cdot 2}{12\cdot 2}= \frac{10}{24} \\ \frac{1}{8}= \frac{1\cdot 3}{8\cdot 3}= \frac{3}{24}$
$\frac{13}{12}= \frac{13\cdot 3}{12\cdot 3}= \frac{39}{36}, \\ \frac{13}{18}= \frac{13\cdot2}{18\cdot 2}= \frac{26}{36}$
$\frac{8}{33}= \frac{8\cdot7}{33\cdot7}= \frac{56}{231}, \\ \frac{9}{77}= \frac{9\cdot3}{77\cdot3}= \frac{27}{231},$
$\frac{10}{297} = \frac{10\cdot 11}{3\cdot 9\cdot11\cdot11}= \frac{110}{3267} , \\ \frac{14}{363} = \frac{14\cdot 9}{3\cdot 11\cdot11\cdot9}= \frac{126}{3267} ,$
