简便计算0.25x3.2x丨 25

展开全部0.25x3.2x1.25=0.25x4x0.8x1.25=(0.25x4)x(0.8x1.25)=1x1=1

=1.25*0.8*(4*25) =1*100 =100

=1.25*0.8*4*25=1*100=100

0.25x3.2x12.5=(0.25*4)*(0.8*12.5)=1*10=10

你好!1.25x3.2x0.25=1.25x8x0.4x0.25=10x0.1=1 0.29x102=0.29x(100+2)=0.29x100+0.29x2=29+0.58=29.58 如有疑问,请追问.

1.25X3.2X0.25=1.25X(8X0.4)X0.25=(1.25X8)X(0.4X0.25)=10X0.1=1

=0.4x0.25+0.4x25=0.1+10=10.1

你好!0.125.5x25=53.25x8:答案是53.125答解仅代表个人观点,不喜勿喷,谢谢.

12.5x0.25x3.2=12.5*0.25*0.8*4=(12.5*0.8)*(0.25*4)=10*1=10 12.5x4.5+4.5x12.5+12.5=12.5*(4.5+4.5+1)=12.5*10=12.5

25%=1/425%x3.2x25%=3.2÷4÷4=0.8÷4=0.2 亲,请【采纳答案】,您的采纳是我答题的动力,谢谢.
