3.47 3.04x9.5的简便方法

简便计算过程方法如下解:3.47+3.04*9.5=3.47+3.04*(10-0.5)=3.47+30.4-3.04*0.5=3.47+30.4-1.52=3.47-1.52+30.4=32.35

10.1x9.5的简便方法10.1x9.5=9.5*(10+0.1)=9.5*10+9.5*0.1=95.95

10.2*9.5-9.5=9.5*(10.2-1)=9.5*9.2=10*9.2-0.5*9.2=92-4.6=87.4

=(1一0,01)x9.5=9.5x1一0.01x9.5=9.5一0.095=9.405

0.51÷0.17*9.5=3*9.5=28.5希望能帮到你谢谢

用简便方法计算6.08x9.5+ 6o8x0.4+ 0.608=6.08*(9.5+0.4+0.1)=6.08*10=60.8

0.25*3.6*9.5=(0.25x0.4)x(9x9.5)=0.1x85.5=8.55

展开全部4.67*0.05+0.467*9.5=4.67*0.05+4.67*0.95=4.67x(0.05+0.95)=4.67x1=4.67

10.5*9.5=(10+0.5)*9.5=10*9.5+0.5*9.5=95+4.75=99.75

3.25X4.78X4=(3.25X4)X4.78=(3X4+0.25X4)X4.78=13X5-13X0.22=65-13X0.2-13X0.02=65-2.6-0.26=65-2.86=65-3+0.14=62.14
