Observe a column of numbers arranged according to the following rules: (1/1), (1/2), (2/1), (1/3), (2/2), (3/1), (1/4 ), (2/3), (3/2), (4/1), ... In the series, the mth number from the left is recorded as F(m), when m=what, F(m)= (2/2011).
观察按下列规则排成的一列数：(1/1)，(1/2)，(2/1)，(1/3)，(2/2)，(3/1)，(1/4)，(2/3)，(3/2)，(4/1)，…在数列当中，从左起第m个数记作F(m)，当m=多少时，F(m)=(2/2011)．
