2.69*4.56+4.56*6.33+4.56,5.45*24*0.2-3.45*4.8,4.26*52.7+35.2*5.27+0.222*527,用简便方法计算
1.一是用计算机.(哈哈!)
2.一,先放上括号:(2.69*4.56)+(4.56*6.33)+(4.56)+(5.45*24*0.2)-(3.45*4.8)+
( 4.26*52.7)+(35.2*5.27)+(0.222*527)
二,把四点五六的放在一起:4.56*(2.69+6.33+1) +(5.45*24*0.2)-(3.45*4.8)+
( 4.26*52.7)+(35.2*5.27)+(0.222*527)
三,先不着急求出答案,现在注意52.7,5.27和527 :4.56*10.02 +(5.45*24*0.2)-(3.45*4.8)+ ( 4.26*52.7)+(35.2*5.27)+(0.222*527)
四,先把这三个括号去掉:4.56*10.02 +(5.45*24*0.2)- (3.45*4.8)+ 4.26*52.7+ 35.2*5.27+ 0.222*527
五,然后再分配:4.56*10.02 +(5.45*24*0.2)- (3.45*4.8)+ 4.26*5.27+ 35.2*52.7+ 0.222*527
六,最后试着把小数点该去掉:4.56*10.02 +(5.45*24*0.2)- (3.45*4.8)+ 4.26*5.27+ 35.2*52.7+ 0.222*527
七,反正最后答案是582.2912

七,反正最后答案是582.2912
2.69*4.56+4.56*6.33+4.56,5.45*24*0.2-3.45*4.8,4.26*52.7+35.2
(1+3.78+4.56)×(3.78+4.56+0.2)-(1+3.78+4.56+0.2)×(3.78+4.56)
(-2.4)+4.56+(-5.6)+(-4.56)
5.45×24×0.2-3.45×4.8=______.
4.8少一个5%是不是等于4.56
4.56×99+4.56用简便计算
4.56=?秒
7.8+4.56+2.2
4.56计数单位
用简便方法计算.4.56×0.27+4.56×0.63+0.456
简算7.56+2.78-4.56+3.22
怎么把4.56化成分数
