1.25*0.2*50*8 =(1.25x8)x(0.2x50) =10x10 =100 很高兴为您解答,祝你学习进步>学习宝典】团队为您答题。 有不明白的可以追问!如果您认可我的回答。 请点击下面的【选为满意回答】按钮,谢谢!

48×1.25+50×1.25×0.2×8简便计算 =1.25x8x6+(50x0.2)x(1.25x8) =10x6+10x10 =60+100 =160

4.8×1.25+50×1.25×0.2×8简便计算 =1.25x8x0.6+(50x0.2)x(1.25x8) =10x0.6+10x10 =6+100 =106

(2.5×1.25)×0.8 =2.5×(1.25×0.8) =2.5×1 =2.5

1.25*500*0.2*8 =(1.25*8)*(500*0.2) =10*100 =1000

(12.5+1.25)*0.8 =(12.5+1.25)*4*0.2 =(12.5*4+1.25*4)*0.2 =(50+5)*0.2 =11

满意请采纳

1.25×0.5×8×0.2 =(1.25×8)×(0.5×0.2) =10×0.1 =1

简便运算 1.25×1.2×0.8 =1.25×0.8×1.2 =1×1.2 =1.2

0.25*0.8*1.25*1.2的简便运算 0.25*0.8*1.25*1.2 =(0.25*4*0.3)*(1.25*0.8) =0.3*1 =0.3
