32x2.5x1.25脱式计算

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

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

(8×4)×125×25 =4×25×8×125 =100×1000 =100000

32X18一28x11 =576-308 =268

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!

12.48÷(32×8分之3+3.6) =12.48÷(12+3.6) =12.48÷15.6 =0.8 不能简便计算。
