中科新闻网水幕喷头是闭式喷头吗:本人碰到一道奥数题，请各位看到的老师帮忙！小弟先谢过了！

题目为：
(1+1/(2*3)+1/(3*5)+1/(4*7)+1/(5*9)+...+1/(50*99))/(1/51+1/52+1/53+1/54+1/55+...+1/100)
即：(1+1/(2*3)+1/(3*5)+1/(4*7)+1/(5*9)+...+1/(50*99))除以(1/51+1/52+1/53+1/54+1/55+...+1/100)的结果
(1+1/(2*3)+1/(3*5)+1/(4*7)+1/(5*9)+...+1/(50*99))/(1/51+1/52+1/53+1/54+1/55+...+1/100)
即：(1+1/(2*3)+1/(3*5)+1/(4*7)+1/(5*9)+...+1/(50*99))除以(1/51+1/52+1/53+1/54+1/55+...+1/100)的结果
可以用简便方法＋计算器
