650÷25+26×99脱式计算能简算的要简算

650÷25+26×99 =26+26x99 =26x(1+99) =26x100 =2600 如有帮助请采纳, 如对本题有疑问可追问,Good luck!

①25×6×15×4=(25×4)×(6×15)=100×90=9000;②26×99+26=26×(99+1)=26×100=2600;③3.85-0.64+0.15-0.36=(3.85+0.15)-(0.64+0.36)=4-1=3;④5÷7-(928+328)=5÷7-37=57-37=27.

解:62X26一25 =(60十2)X26一25 =60X26十2X26一25 =1560十52一25 =1560一25十52 =1535十52 =1587

(1)89+124+11+26+48=(89+11)+(124+26+48)=100+198=298;(2)(64-224÷14)×12=(64-16)×12=48×12=576;(3)120×(38+405÷27)=120×(38+15)=120×53=6360;(4)163×25+237×25=(163+237)×25=400×25=10000;(5)384+98×25×4=384+98×...

(1)1.85×2.5+2.15×2.5=(1.85+2.15)×2.5,=4×2.5,=10;(2)81.99÷0.9×0.17=91.1×0.17,=15.487;(3)18.26-2.35-4.65=18.26-(2.35+4.65),=18.26-7,=11.26;(4)1.25×32×0.25=(1.25×8)×(4×0.25),=10×1,=10;(5)31.6÷1.25÷8=3...

32×125×25 =4×8×125×25 =(4×25)×(8×125) =100×1000 =100000 9048÷26 =(2600+2600+2600+1248)÷26 =2600÷26+2600÷26+2600÷26+1248÷26 =100+100+100+48 =348 2881÷ 43 =(1290+1591)÷ 43 =1290÷43+1591÷43 =30+37 =67 3.2×42.3×3.75-12.5×0....

25×28×4=28*(25*4)=28*100=2800 125×26×5×8=(125*8)*(26*5)=1000*130=130000 4×36×5×3=36*(4*5*3)=36*60=2160 567-(357+205)=567-357-205=210-205=5
