1 / (1 / 2) + 1 / (2 * 3) + 1 / (3 * 4) +... + / (2007 + 2008) = / is division sign, * is multiplication sign, online, etc., the best solution 1 / (1 / 2) + 1 / (2 * 3) + 1 / (3 * 4) +. + / (2007 + 2008) = / is division sign, * is multiplication sign, online, etc., the best solution

In fact, it's very simple, big brother or big sister
S = (1-1 / 2) + (1 / 2-1 / 3) + (1 / 3-1 / 4) +... + (1 / 2007-1 / 2008) = 1-1 / 2008 = 2007 / 2008
