脱式计算 9.8除3.5 0.85除2.5乘4

2.8 1.36

  3.6×(9.8÷0.3×4)=3.6×9.8÷0.3×4=3.6÷0.3×4×9.8=12×4×9.8=470.4

脱式计算 (4.9+9.8)÷4 =14.7÷4 =3.675

9.8除【2.5减(0.95加1.3)】 =9.8÷【2.5-2.25】 =9.8÷0.25 =39.2

9.8÷7.3×(5.3-2.5) =9.8÷7.3×2.8 =9.8×2.8÷7.3 =27.44÷7.3 =1372/365

2012年1月28日星期六一、口算题小数加法:0.3+1.5=2.5+9.8=7.6+1.3=4.4+5.7=2.3+7.7=5.7+3.1=7.69+2.31=9.16+2.64=5.68+12.22=16.8+16.5=小数减法:6.8-3.8=4.26-3.71=0.88-2.12=5.34-69.21=68.4-61.5=9.58-3.7=18.94-5.66=15.69-9.78=115-68.59...

180÷9x8 =20x8 =160 朋友,请及时采纳正确答案,下次还可能帮到您哦,您采纳正确答案,您也可以得到财富值,谢谢。

0.75x8/9÷3/4 =0.75÷3/4x8/9 =8/9

9.9*4.8+0.48 =0.48*(99+1) =0.48*100 =48

一、5.4÷1.8+240×1.5 =3+360 =363 二、9000÷72×(1.25×0.7×8) =9000÷72×7 =125×7 =875 三、61-(1.25+2.5×0.7) =61-3 =58 四、[(10-0.8)+9.85]-2÷0.125 =19.05-2÷0.125 =19.05-16 =3.05 1、脱式计算,即递等式计算,需将一系列的数字逐步计算。在...
