2010÷2010又2011分之2010＋2012分之1
=2010 ÷ (2010 + 2010/2011) + 1/2012
=2010 ÷ (2010x2111 + 2010)/2011 + 1/2012
=(2010 x 2011)/(2010x2111 + 2010) + 1/2012
=(2010 x 2011)/2010x(2111 + 1) + 1/2012
=(2010 x 2011)/(2010x2112 + 1/2012)
=(2010 x 2011)/(2010x2112 + 2010/2010x2012)
=(2010 x 2011 + 2010 )/(2010x2012)
=2010 x (2011 +1)/(2010x2012)
= (2010 x 2012) / (2010x2012 )
= 1請問有沒有簡便計算這就是簡便計算啊，我寫清楚點(diǎn)怕你看不懂。。-_-那我簡化點(diǎn)步驟 2010÷2010又2011分之2010＋2012分之1=2010÷(2010x2111 + 2010)/2011 + 1/2012=(2010x2011)/(2010x2111 + 2010) + 1/2012=(2010x2011)/2010x(2111 + 1)+ 1/2012=(2010x2011)/(2010x2112)+ 1/2012=(2010x2011+ 2010 )/(2010x2012) =2010x(2011+1)/(2010x2012) = (2010 x 2012) / (2010x2012 )=1好吧，雖然有些長，不過上面的更不靠譜
