2.5*2.7*0.4125*32*0.25 =2.5*2.7*0.4125*（4*4*2）0.25 =2.5*4*0.4125*2*0.25*4*2.7 =10*0.825*1*2.7 =8.25*2.7 =8.25*（2+0.7）8.25*2+8.25*0.7 =16.5+5.775 =22.275
＝（4×0.25）×（8×12.5）＝1×100 ＝100
32x0.25x12.5 9.6x28.5+0.285x40 用简便方法计算(要过程) -
32*0.25*12.5 =(8*4)*0.25*12.5 =(8*12.5)*(0.25*4)=100*1 =100
32×0.25×12.5 ＝4×8×0.25×12.5 ＝（4×0.25）×（8×12.5）＝1×100 ＝100

简便计算32x0.25x1.25 =4x8x0.25x1.25 =（4x0.25）x（8x1.25）1x10 =10
12.75-4.62-3.38+7.25=(12.75+7.25)-(4.62+3.38)=20-8=12 10.5x0.8+1.5x0.8+0.8=0.8 x (10.5 + 1.5 + 1)=0.8 x 13=10.4 1.25x32x0.25 = (1.25 x 8) x (4 x 0.25)=10 x 1=10
32×0点25×6用脱式简便运算怎么写? -
32×0.25×6 ＝4×8×0.25×6 ＝8×6×(4×0.25)＝48×1 ＝48
9.2x9.9 =9.2x(10-0.1)=9.2x10-9.2x0.1 =92-0.92 =91.08 1.25x32x0.25 =1.25x8x4x0.25 =10x1 =10
