## Description
<section id="description"> Рассмотрим диофантово уравнение 1 / a + 1 / b = p / 10n с a, b, p, n положительными целыми числами и a ≤ b. При n = 1 это уравнение имеет 20 решений, которые перечислены ниже: 1/1 + 1/1 = 20/10 1/1 + 1/2 = 15/10 1/1 + 1/5 = 12/10 1/1 + 1/10 = 11/10 10/10 1/2 + 1 / / 10 1/3 + 1/15 = 4/10 1/4 + 1/4 = 5/10 1/4 + 1/20 = 3/10 1/5 + 1/5 = 4/10 1/5 + 1/10 = 3/10 1/6 + 1/30 = 2/10 1/10 + 1/10 = 2/10 1/11 + 1/110 = 1/10 1/12 + 1/60 = 1 / 10 1/14 + 1/35 = 1/10 1/15 + 1/30 = 1/10 1/20 + 1/20 = 1/10 Сколько решений имеет это уравнение для 1 ≤ n ≤ 9? </section>
