5.8*0.29+7.1*0.58 怎样简便计算
5.8*0.29+7.1*0.58 怎样简便计算

5.8*0.29+7.1*0.58 怎样简便计算
5.8*0.29+0.71*5.8=5.8*1=5.8

0.58x2.9+7.1x0.58
=0.58x(2.9+7.1)
=0.58x10
=5.8

解:
原式=5.8×0.29+5.8×0.71=5.8×(0.29+0.71)=5.8×1=5.8
仅供参考……

您好
5.8*0.29+7.1*0.58
=5.8*0.29+0.58*7.1
=5.8*0.29+0.58*10*(1/10)*7.1
=5.8*0.29+(0.58*10)*[(1/10)*7.1]
=5.8*0.29+5.8*0.71
=5.8*(0.29+0.71)
=5.8*1
=5.8
希望能帮到您,请采纳,谢谢!

5.8*0.29+0.71*5.8
=5.8

=0.58X2.9+7.1X0.58
=0.58X(2.9+7.1)
=0.58X10
=5.8
