75%乘1.375加5.625乘75%加0.75(简便运算)

0.75+5.625×4分之3+75%×1.375 =0.75×(1+5.625+1.375) =0.75×8 =6

=0.75*(1.375 5.625 1) =0.75*8 =6

八分之五和百分之62.5都是0.625,这个式子中就有了三个0.625,把0.625提出来,把二分之一变成0.5,即=0.625*(0.5+1+0.5)=0.625*2=1.25

5/8×3/10+0.625×0.6+62.5%×0.1 =0.625×0.3+0.625×0.6+0.625×0.1 =0.625×(0.3+0.6+0.1) =0.625×1 =0.625

75%x3.14+5.625x75%+0.75=0.75x(3.14+5.625+1)=0.75*9.765=7.32375

4分之7乘以8分之5加4分之1除以5分之8 =4分之7乘以8分之5加4分之1乘以8分之5 =(4分之7加4分之1)乘以8分之5=2乘以8分之5 =4分之5

详细步骤写在纸上了

27.5-0.375-(1.625-0.25) =27.5-(0.375+1.625)+0.25 =27.5-2+0.25 =25.5+0.25 =25.75 你好,本题已解答,如果满意 请点右上角“采纳答案”。

解:12分1之乘0.625加8分之5乘12分之5加2分之1除5分之8 =12分之1乘16分之1加96分之25+2分之1乘8分之5 =192分之1+25/96+4/5 =51/192+4/5 =1023/960 =341/320

四分之三除以8/5+4分之1×0点625的简便运算 四分之三除以8/5+4分之1×0点625 =5/8*(3/4+1/4) =5/8*1 =5/8
