列竖式计算25.5/6

望采纳谢谢

25.5÷6 =4.25 竖式请见图:

2.6 × 5.25 = 13.65 竖式见图:

5/3×25×6/5×4列式计算答案 5/3×25×6/5×4 =5/3x6/5x(25x4) =2x100 =200

用竖式进行乘法运算时其实用的是乘法对加法的分配律: (a+b)*c=ac+bc;(a+b)*(c+d)=(a+b)*c+(a+b)*d=ac+bc+ad+bd. 12*25用竖式时计算: 1 2 ×2 5 6 0 2 4 0 3 0 0 60那行其实中12*5,240那行其实是12*20,所以12*25=12*5+12*20=300

25×5÷6 =5×6 =30

6.7+2.53=9.23验算:5.25-0.7=4.55验算:

72÷15=4.8 14.21÷7=2.03 25.5÷6=4.25
