32x2.5x1.25脱式计算

32x2.5x1.25脱式计算 =8x4x2.5x1.25 =(8x1.25)x(4x2.5) =10x10 =100

32X0.25X1.25脱式计算 32X0.25X1.25 =(0.25*4)*(1.25*8) =1*10 =10

25x18x32x225 =25×18×4×2×4×25×9 =(25×4)×(25×4)×(18×2×9) =100×100×324 =3240000 希望对你有帮助!

=300-1-32x(20-1) =300-32x20+32x1+1 =300-640+33 =33-340 =-307

12.32x1.7一12.32x0.7 =12.32x(1.7-0.7) =12.32x1 =12.32

32X18一28x11 =576-308 =268

12.5x32x0.125 =12.5x(4x8)x0.125 =(12.5x4)x(8x0.125) =50x1 =50 运用乘法结合律。 希望能帮到你!

125*8*4*25

480+32x|4-280的脱式计算 480+32x|4-280 =480-280+448 =200+448 =648

原式=32x2+32x12 =32x(2+12) =32x14 =(30+2)x14 =30x14+2x14 =420+28 =448
