| ## Description
 | ||
| <section id="description">分子小于其分母的正分数称为适当分数。对于任何分母,d,将有d-1个适当的分数;例如,d = 12:1 / 12,2 / 12,3 / 12,4 / 12,5 / 12,6 / 12,7 / 12,8 / 12,9 / 12,10 / 12,11 / 12。 <p>我们将称一个无法取消弹性部分的分数。此外,我们将分母R(d)的弹性定义为具有弹性的适当分数的比率;例如,R(12)= 4/11。事实上,d = 12是具有弹性R(d)<4/10的最小分母。 </p><p>找到最小分母d,具有弹性R(d)<15499/94744。 </p></section>
