(12345+23451+34512+45123+51234)/(11111+22222)简算
注意,这题的简便方法就是交换一下12345+23451+34512+45123+51234
数字的顺序,比如说分别取五个数中的1组成了 11111,然后取五个数中的2组成了 22222.
（12345+23451+34512+45123+51234)/(11111+22222)
=(11111+22222+33333+44444+55555)/33333
=11111×（1+2+3+4+5）/(3×11111)
=11111×15/(3×11111)
=5

(12345+23451+34512+45123+51234)/(11111+22222
=(1+2+3+4+5)*(10000+1000+100+10+1)/(3*11111)
=15*11111/(3*11111)
=15/3=5
