888.8×8-222.2×14-9×444.4 怎样简便计算

888.8×8-222.2×14-9×444.4
=222.2×32-222.2×14-18×222.2
=222.2×（32-14-18）
=222.2×0
=0

359÷27.3×1.254÷718×273÷125.4
=（359÷718）×（273÷27.3）×(1.254÷125.4)
=1/2×10×0.01
=0.5×0.1
=0.05

3又3/5×234+5555÷25/256+654.3×36
=18/5×234+5555×256/25+23554.8
=842.4+56883.2+23554.8
=81280.4

1÷1/2÷2/3÷3/4.÷99/100
=1×2×3/2×4/3..×100/99
=1×100
=100

888.8×8-222.2×14-9×444.4
=444.4×2×8-444.4×7-444.4×9
=444.4×(16-7-9)
=444.4×0
=0
乘法分配律
359÷27.3×1.254÷718×273÷125.4
=359÷718×1.254÷125.4×273÷27.3
=(359÷718)×(1.254÷125.4)×(273÷27.3)
=0.5×0.01×10
=0.05

愿对你有所帮助！

(1)原式=8X111.1X8-2X111.1X14-9X4X1.111=(64-28-36)X111.1=0
(2)原式=(359/718)X(273/27.3)X(1.254/125.4)=1/2X10X0.01=0.05
(3)原式=(3.6X234+3.6X6543)+1111*256/5 可能题目有点不对 还是很难算 括号里算出来至少应该带着X1111才能算得上简便算...

设444.4为X以上算式等于X*2*8-(X/2)*14-9X=16X-7X-9X=0




还带这么补充问题的？放弃......那么简单的题

888.8×8-222.2×14-9×444.4
=444.4×16-444.4×7-9×444.4
=444.4×(16-7-9)
=444.4×0
=0

不懂可追问，有帮助请采纳，谢谢！
