6.8x0.23的简便运算

6.8x0.23的简便运算=6.8x(0.2+0.03)=6.8x0.2+6.8x0.03=1.36+0.204=1.564

解:0.38x0.23 =(0.4-0.02)x0.23 =0.4x0.23-0.02x0.23 =0.092-0.0046 =0.0874 或者0.38x0.23 =0.38x(0.2+0.03) =0.38x0.2+0.38x0.03 =0.076+0.0114 =0.0874

0.38乘0.23用简便方法怎么计算解:0.38乘0.23=(0.4-0.02)*0.23=0.4*0.23-0.02*0.23=0.092-0.0046=0.0874

1.55-0.77+0.77-0.23=1.55-0.23-0.77+0.77=1.55-0.23=1.32希望帮到你 望采纳 谢谢 加油

按运算法则,先算除法再算减法最简便. 52.9-6.9÷0.23=52.9-30=22.9.

9.81x0.23-0.23x6.81=0.23x(9.81-6.81)=0.23x3=0.69

1.81x2.3-23简便计算过程如下1.81*2.3-2.3*10=2.3*(1.81-10)=2.3*(-8.19)=-18.837

5.29-(3.8-0.71)-0.23=5.29-3.8+0.71-0.23=(5.29+0.71)-(3.8+0.23)=6-4.03=1.97

18.75-0.23-4.77解:简便计算=18.75-(0.23+4.77)=18.75-5=13.75祝学习进步.

原式=2.3x6.8+3.1x2.3+0.23=2.3x6.8+3.1x2.3+2.3x0.1=2.3x(6.8+3.1+0.1)=2.3x(9.9+0.1)=2.3x10=23
