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

4.3×0.625+3.75×0.43 =0.43×6.25+3.75×0.43 =0.43×(6.25+3.75) =0.43×10 =4.3

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

①9.8÷2.5÷0.4=9.8÷(2.5×0.4)=9.8÷1=9.8;②0.8×(0.175×1.25)=(0.8×1.25)×0.175=1×0.175=0.175;③16.8÷1.25÷0.8=16.8÷(1.25×0.8)=16.8÷1=16.8;④(34.28+45.43)÷0.5 =79.71÷0.5=159.42;⑤28.8×(4.8÷1.2)=28.8×4=115.2;⑥116.9÷0.7-85.6...

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...

6.49X5.7+0.43X64.9 =6.49X5.7+0.43X(10X6.49) =6.49X5.7+(0.43X10)X6.49 =6.49X5.7+4.3X6.49 =6.49X(5.7+4.3) =6.49X10 =64.9

33.2 解析: 43.2-1.8×3-4.6 =43.2-(5.4+4.6) =43.2-10 =33.2

(1)21÷0.25÷0.4=21÷(0.25×0.4)=21÷0.1=210(2)3.5×0.7+5.5×0.7+0.7=(3.5+5.5+1)×0.7=10×0.7=7(3)14.5×102=14.5×100+14.5×2=1450+29=1479(4)0.125×3.2×0.25=(0.125×8)×(0.4×0.25)=1×0.1=0.1(5)64×4.5+3.6×45=(6.4+3.6)×45=10×...
