4.68乘以十五点二加46点八乘以八点四八用简便方法...

4.68*15.2+46.8*8.48=4.68*15.2+4.68*84.8=4.68*(15.2+84.8)=4.68*100=468

0.5*2.33*8=0.5*8*2.33=4*2.33=9.32乘法交换律供参考,有疑问请追问

原式等于0.84*(1.2+8.8)=0.84*10=8.4所以原式的计算结果为8.4

4.3x1.8+0.82x43=43x0.18+0.82x43=(0.18+0.82)x43=1x43=43

1.68乘以48+4点8*13点二=16.8*4.8+4.8*13.2=4.8*(16.8+13.2)=4.8*30=144

9.9x4.8+0.48 =4.8x(9.9+0.1) =4.8x10 =48如有帮助请采纳, 如对本题有疑问可追问,Good luck!

8.4*7.2+0.84*28 =0.84*72+0.84*28 =0.84*(72+28) =0.84*100 =84

答:13.8*6.48+13.8*3.52 =13.8*(6.48+3.52) =13.8*10 =138

46*0.28+2.8*5.4=46+0.28+0.28*54=(46+54)*0.28=100*0.28=28

原式=4.8*(0.6+8.4+9.6)=4.8*18.6=89.28
