1.25×0.43×0.08的脱式计算

1.25×0.43×0.08 =1.25×0.08×0.43 =0.1×0.43 =0.043

0.43*1.8÷0.43*1.8 =(0.43÷0.43)*(1.8*1.8) =1*3.24 =3.24

4.3x9.9+0.43 =4.3x(9.9+0.1) =4.3x10 =43

脱式怎么计算 2.8×1.43+0.57×2.8 =2.8×(1.43+0.57) =2.8×2 =5.6

(1)15×43%+85×0.43=15×0.43+85×0.43,=(15+85)×0.43,=100×0.43,=43;(2) 7 9 ÷ 11 5 + 2 9 × 5 11 = 7 9 × 5 11 + 2 9 × 5 11 ,=( 7 9 + 2 9 )× 5 11 ,=1× 5 11 ,= 5 11 ;(3)( 1 2 - 1 3 )× 3 8 ÷25%=( 3 6 - 2 6 )× 3 8 ÷...

(1)15×43%+85×0.43=15×0.43+85×0.43,=(15+85)×0.43,=100×0.43,=43;(2)79÷115+29×511=79×511+29×511,=(79+29)×511,=1×511,=511;(3)(12-13)×38÷25%=(36?26)×38÷14,=16×38×4,=14.

38*(57+43)=38*100=3800 乘法结合律

简算 73x43+27x46 =73x43+27x43+27x3 =(73+27)x43+81 =4300+81 =4381 满意请采纳,谢谢

1. 0.4×125×25×0.8 =(0.4×25)×(125×0.8)=10×100=1000 2. 1.25×(8+10)=1.25×8+1.25×10 =10+12.5=22.5 3.9123-(123+8.8)=9123-123-8.8=9000-8.8=8991.2 4.1.24×8.3+8.3×1.76 =8.3×(1.24+1.76) =8.3×3=24.9 5.9999×1001=9999×(1000+1)=...

408-12×24 = 408 - 288 = 120 (46+28)×60 = 74 x 60 = 4440 42×50-17 = 2100- 17 = 2083 32+105÷5 = 32 + 21 = 53 420×(327-238) = 420 x 89 = 37380 (4121+2389)÷7 = 6510 ÷7 = 930 3.416÷(0.016×35) = 3.416 ÷0.56 = 6.1 0.8×[(10...
