와 엔딩이댜!! (여기 클릭하면 엔딩)
문제가 해당하는 번호가 써있는 문을 열었다.
생각했던 듯이, 범인이 서 있었다.
그는 칼을 들고, 웃음을 지었다.
웃음에서 마치 "너 같은 애송이는 한방이면 끝나겠는걸" 이라는 말이 들리는 것 같았다.
그러나, 나는 망설이지 않았다.
그의 몸에, 수학 문제가 써져있는 영혼이 보였다.
저걸 풀면, 그의 악의도 사라질 것이다.
< 문 제 >
분모가 2부터 31,415 까지인 분수 중
약분이 불가능한 분수의 개수는?
(예: 2분의 1 같은 경우 약분이 불가능함)
* 이 문제에서는 약분에서 분모와 분자를 나누는 수는 자연수여야 한다.
*조건 추가! 분자도 2부터 31415까지 중 하나여야 함.
