A list of fractions is known to be arranged in the following order: (1/1), (1/2), (2/2), (1/2), (1/3), (2/3), (3/3) , (2/3), (1/3), (1/4), (2/4), (3/4), (4/4), (3/4), (2/4), ( 1/4), ..., then the number (12/12) ranks in this column of scores.
已知一列分数按以下规律排列：(1/1)、(1/2)、(2/2)、(1/2)、(1/3)、(2/3)、(3/3)、(2/3)、(1/3)、(1/4)、(2/4)、(3/4)、(4/4)、(3/4)、(2/4)、(1/4)、…，那么数(12/12)排在这列分数的第多少个．
