45.6X6.7十4.56X33简便计算

1.9*4.5+0.45 =4.5*(1.9+0.1) =4.5*2 =9 希望我的回答对您有帮助,有问题可以追问. 满意请及时采纳,谢谢!

原式=4.56*(67+31+2)=4.56*100=456

2.5X3.6、=2.5X0.4X9=1X9=916.3X9.9=16.3X(10-1)=16.3X10-16.3X1=163-16.3=161.376.2X11+6.2X88+6.2=6.2X(11+88+1)=6.2X100=62045.6x6.7+4.56x33=45.6x6.7+45.6x3.3=45.6x(6.7+3.3)=45.6x10=456

45.6x4.56简便运算45.6x4.56=207.936直接计算没有简算

45.6*6.7+4.56*33=45.6*6.7+45.6*3.3=45.6*(6.7+3.3)=45.6*10=456

4.56*31 = 45.6 x 3.10.456*20= 45.6 x 0.2所以,原式 = 45.6*6.7+ 45.6 x 3.1+45.6 x 0.2=45.6x(6.7+3.1+0.2)=45.6x10=456

你好!原式=45.6x6.7+45.6x3.1+45.6x0.2=45.6x(6.7+3.1+0.2)=45.6x(9.8+0.2)=45.6x10=456供参考.仅代表个人观点,不喜勿喷,谢谢.

45.6*6.7+4.56*31+0.45*20=4.56*10*6.7+4.56*31+0.45*20=4.56*(67+31)+0.45*20=4.56*98+0.45*20=4.56*(100-2)+0.45*20=456-4.56*2+0.45*20=456+2*(0.45*10-4.56)=456+2*(-0.06)=456-0.12=455.88
