32×1.25脱式计算

2.5×1.25×32 =2.5×4×1.25×8 =10×10 =100

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

1.25×32×12.5%?脱式计算 1.25×32×12.5%? =1.25*8*4*0.125 =10*0.5 =5

1.25x32 =1.25x8x4 =10x4 =40

1.25×32×2.5 =(1.25×8)×(4×2.5) =10×10 =100 你好,本题已解答,如果满意 请点右上角“采纳答案”。

0.25×6.4×1.25 =0.25×8x0.8×1.25 =(0.25×8)x(0.8×1.25) =2x1 =2 希望帮到你 望采纳 谢谢 加油

1.25×49+1.25 =1.25×(49+1) =1.25×50 =62.5

脱式计算能简算的要简算2.5×1.6×1.25 2.5×1.6×1.25 =2.5×2×0.8×1.25 =5×1 =5

(1)0.25×1.25×4×8,=(0.25×4)×(1.25×8),=1×10,=10;(2)2.125×14+1.875÷4,=(2.125+1.875)×14,=4×14,=1;(3)(2.5-0.125)×0.8+6.24,=2.5×0.8-0.125×0.8+6.24,=2-0.1+6.24,=8.14,(4)2÷23-23÷2,=2×32-23×12,=3-13,=223;...

(1)1305-386-614,=1305-(386+614),=1305-1000,=305;(2)(14+23-56)×12,=14×12+23×12-56×12,=3+8-10,=1; (3)1.25×32×2.5,=(1.25×8)×(4×2.5),=10×10,=100;(4)10.9-(45+9.6÷4),=10.9-(45+2.4),=10.9-3.2,=7.7.
