$n:21\frac{6}{23}-\frac{1}{47}m$ at $n=97,8m=31\frac{1}{3}$
$97\frac{8}{10}:21\frac{6}{23}-\frac{1}{47}\ast 31\frac{1}{3}=$
$\frac{489}{5}\ast \frac{23}{489}-\frac{1}{47}\ast \frac{94}{3}=$
$\frac{489}{5}\ast \frac{23}{489}-\frac{1}{47}\ast \frac{94}{3}=\frac{23}{5}-\frac{2}{3}=$
$=\frac{69-10}{15}=\frac{59}{15}=3\frac{14}{15}$
