1.25×0.43×0.08的脱式计算

5.4x(0.78-0.43) =5.4*0.35 =1.89

1. 4×102-2×49 =408-2×49 =408-98 =310 2. 25×(2+4) =25×2+25×4 =50+100 =150 3. 12×5+8 =60+8 =68 4. 99×101 =99×(100+1) =99×100+99×1 =9900+99 =9999 5. 25×(78×4) =25×4×78 =100×78 =7800 6. (25+12)×4 =25×4+12×4 =100+48 =148 7. ...

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

3.7×1.43 0.57脱式计算 =2.7x1.43+(1.43+0.57) =3.861+2 =5.861

你好,很高兴为你解答 脱式计算 2.8×1.43+0.57×2.8能简算的要简算。 =2.8x(1.43+0.57) =2.8x2 =5.6 满意采纳哦!

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)1.43×[(2.8+4.4)÷1.2]=1.43×[7.2÷1.2]=1.43×6=8.58;(2)8.4+17.85+12.6+2.15=(8.4+12.6)+(17.85+2.15)=21+20=41;(3)2.5×5.6×0.4=2.5×0.4×5.6=1×5.6=5.6;(4)3.6÷[1.8×(3.4-2.9)]=3.6÷[1.8×0.5]=3.6÷0.9=4.

2.8×1.43+ 0.57 =4.004+0.57 =4.574

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)=...
