0.125乘4分之3加8分之1乘8.25加0.125=0.125×0.75+0.125×8.25+0.125=0.125×(0.75+8.25+1)=0.125×10=1.25

0.125乘4分之3加8分之1乘8.25加12.5％=0.125×(3/4+1+8.25)=0.125×10=1.25不懂可追问,有帮助请采纳,谢谢!再问：0.125×(3/4+1+8.25)1从哪里

0.9乘8.4加1乘0.84=9×0.84+0.84=（9+1）×0.84=10×0.84=8.472乘1.25=9*（8*1.25）=9*10=900.36乘2.4加76乘0.036=0.36×2.

146除以1.25加15.4乘以8146÷1.25+15.4×8=14.6×8+15.4×8=（14.6+15.4）×8=30×8=240

0.125乘34加18乘8.25加12.5%=0.125*34+18*8.25+12.5%=0.125*35+(20-2)*8.25=0.125*8*4.375+165-16.5=4.375+165-

0.125^2+2*0.125*0.875+0.875^2=(0.125+0.875)^2=1^2=1

0.91乘99加91乘0.01=0.91*（99+1）=0.91*100=911.25乘88加12除以5分之4=1.25*88+12*1.25=1.25*（88+12）=1.25*100=125

32x1.25+12.5x6.8=32x1.25+68x1.25=(32+68)x1.25=100x1.25=125
