12.6x7.6x2.32➗1.9➗1.4➗2.9如何用简便计算? 12.6x7.6x2.32➗1.9➗1.4➗2.9 =(12.6÷4)*(7.6÷1.9)*(2.32÷2.9) =3.15*4*0.8 =10.08

0.8x0.25x0.4x12.5 4.58➗2.5➗0.4 都简便计算过程具体 0.8x0.25x0.4x12.5 =(0.8*12.5)*(0.25*0.4) =10*0.1 =1 4.58➗2.5➗0.4 =4.58÷(2.5*0.4) =4.58÷1 =4.58

2.1*5.1 *159.1➗0.7➗1.7➗3.7 =(2.1➗0.7)*(5.1 ➗1.7)*(159.1➗3.7) =3x3x43 =387

5➗(7➗11)➗(11➗16)➗(16➗35)简便方法 5➗(7➗11)➗(11➗16)➗(16➗35) =(11÷11)*(16÷16)*(35*5÷7) =1*1*25 =25

结合律。 列式为: 2100➗42 =2100➗(7x6) =2100➗7➗6 =300➗6 =50

解:9000000➗25➗125➗8➗5➗4➗2 =9000000➗(25x125x8x5x4x2) =9000000➗(25x4x5x2x125x8) =9000000➗(100x10x1000) =9

450除以五再除以九怎么用简便方法算 450➗5➗9 =450➗(5x9) =450➗45 =10

450➗3➕450➗2简便方法 450➗3➕450➗2 =450*(3+2) =450*5 =2250

(980-184-16)➗35 =[980-(184+16)]➗35 =[980-200]➗35 =780➗35 =(770+10)➗35 =770➗35+10➗35 =22+2/7 =22又2/7

250+616➗28x15 =250+616➗7➗4x15 =250+88➗4x15 =250+22x15 =250+22x5x3 =250+110x3 =250+330 =580
