=11.7*57*85/1.7/1.9/13/5/3=11.7*57*50/1.9/13/5/3=11.7*19*10/1.9/13=11.7/13*100=90

7.29乘4.6加46乘1.271=0.729×46+46×1.271=(0.729+1.271)×46=2×46=929.6乘3.6加8.2乘0.2=9.6×9×0.4+4.1×0.4=(9.6×9

=5.4×20=108如果我的回答能够解决你的问题,如果有疑问继续追问,衷心感谢你的支持再问：要简算再答：5.4×（16.4+4.6-1）=5.4×20=108

5.4乘5分之4加1.25乘3.2减0.6乘125％=5.4*4/5+1.25*3.2-0.6*1.25=(5+0.4)*0.8+1.25*(3.2-0.6)=4+0.4*0.8+1.25*2.6=4

1.原式=3.6*4.7+3.6*5.1+3.6*0.2=3.6*（4.7+5.1+0.2）=3.6*10=362.原式=1.2*3.8+1.2*3.8+1.2*24=1.2*（3.8+3.8+24）

0.56*202=0.56*200+0.56*2=112+1.12=113.124.8*0.125=0.6*8*0.125=0.6*1=0.64.6*1.9+5.4*1.9=1.9*(4.6+5.4)

12.35*37-123.5*1.9+1.235*820=12.35*37-12.35*19+12.35*82=12.35*（37-19+82）=12.35*100=1235

537.5再问：我也知道可是不知道算式再答：十么算式（你能说明白点再问：当然是怎么算的，过程再答：41.2*8.1+11*9.25+53.7*1.9=记住先乘除后加减先三个乘法分别先乘出来最后将这三个

41.2×8.1+11×1.25+3.7×1.9=354.5再问：有过程吗，要简算

（1×2.3×4.5+3×6.9×13.5）分之（2×4.6×9+4×9.2×18）=1×2.3×4.5×（1+3×3×3）分之【1×2.3×4.5×（2×2×2+4×4×4）】=（1+3×3×3）分

你好!41.2*8.1+11*9.25+53.7*1.9=41.2*8.1+11*9.25+(41.2+12.5)*1.9=41.2*8.1+41.2*1.9+12.5*1.9+11*(1.25+8)

41.2乘8.1加11乘1.25加53.7乘1.9=41.2乘(10减1.9)加11乘1.25加53.7乘1.9=412减41.2乘1.9+53.7乘1.9+11乘1.25=412+12.5乘1.9加

7.5*2.7=2.5*3*2.7=2.5*8.12.5*8.1+1.9*2.5=2.5*(8.1+1.9)=2.5*10=25

369.006

7.6×7.3＋1.9×4×7.3＝7.6×7.3＋7.6×7.3＝2×7.6×7.3＝110.96

41.2×8.1＋11×1.25＋53.7×1.9=41.2×(10-1.9)+53.7×1.9+11×1.25=412+12.5×1.9+1.1×12.5=412+12.5×(1.1+1.9)=41

分解0.9*7*9*3+1.9*21然后21（8.1+1.9）得21*10=210求采纳
