## 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 = 121 / 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Rd的弹性定义为具有弹性的适当分数的比率;例如R12= 4/11。事实上d = 12是具有弹性Rd&lt;4/10的最小分母。 </p><p>找到最小分母d具有弹性Rd&lt;15499/94744。 </p></section>
