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
=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
