## Description
|
|
<section id="description"> Una fracción unitaria contiene 1 en el numerador. La representación decimal de las fracciones unitarias con denominadores 2 a 10 se da: <div style="padding-left: 4em; display: inline-grid; grid-template-rows: auto; row-gap: 7px;"><div> <sup><sub>Media</sub></sup> = 0,5 </div><div> <sup><sub>1/3</sub></sup> = 0. (3) </div><div> <sup><sub>1/4</sub></sup> = 0,25 </div><div> <sup><sub>1/5</sub></sup> = 0,2 </div><div> <sup><sub>1/6</sub></sup> = 0,1 (6) </div><div> <sup><sub>Séptima</sub></sup> = 0. (142857) </div><div> <sup><sub>1/8</sub></sup> = 0,125 </div><div> <sup><sub>1/9</sub></sup> = 0. (1) </div><div> <sup><sub>1/10</sub></sup> = 0,1 </div></div> Donde 0.1 (6) significa 0.166666 ..., y tiene un ciclo recurrente de 1 dígito. Puede ser visto que <sup><sub>1/7</sub></sup> tiene un ciclo recurrente de 6 dígitos. Encuentre el valor de <var>d</var> < <var>n</var> para el cual <sup>1</sup> / <sub>d</sub> contiene el ciclo recurrente más largo en su parte de fracción decimal. </section>
