Question

999999×0.7+11111×3.7简便方法？

Answer 1

本题题目有误，要么是99999，要么是111111
按照99999计算过程如下：
99999×0.7+11111×3.7
=9x11111x0.7+11111x3.7
=11111x(9x0.7+3.7)......提出11111
=11111x(6.3+3.7)
=11111x10
=111110

Answer 2

=1000000*0.7+10000*3.7+1000*3.7+100*3.7+10*3.7+3.7-0.7
=700000+37000+3700+370+37+3.7-0.7
=74110(这个答案有点皮啊）
列竖式很简单的，看着复杂但这样做计算过程很简单

Answer 3

999999*0.7+11111*3.7
=999999*0.7+11111*（3+0.7）
=999999*0.7+11111*0.7+11111*3
=（999999+1）*0.7+11110*0.7+11111*3
=700000+1111*7+1111*3+10000*3
=700000+11110+30000
=741110

Answer 4

999999 × 0.7 + 111111 × 3.7

=111111 × 9 × 0.7 + 111111 × 3.7
=111111 × 6.3 + 111111 × 3.7
=111111 × ( 6.3 + 3.7 )

=111111 × 10
=1111110
请检查题目是否正确。

Answer 5

=999999*0.7+11111*（3+0.7）
=999999*0.7+11111*0.7+11111*3
=（999999+11111）*0.7+33333
=707777+33333
=741110

追答

=999999*0.7+11111*（3+0.7）
=999999*0.7+11111*0.7+11111*3
=（999999+11111）*0.7+33333
=707777+33333
=741110
