0.54除以0.75竖式计算

0.54÷0.75=0.72

0.16

(0.54x0.75x0.48)除以(0.25x0.24x0.27)=0.54x0.75x0.48÷0.25÷0.24÷0.27=(0.54÷0.27)x(0.75÷0.25)x(0.48÷0.24)=2x3x2=12

1.998÷0.54=3.7 竖式如下:

0.54/0.72=6*0.9/8*0.9=6/8=3/4

0.81/0.27=3 0.75/0.25=3 0.84/0.24=7/2原式=3*3*7/2=63/2

解:(2.5*8 )÷(25 *0.8)-0.75 =(2.5x8)/(25x0.8)-0.75 =(25x0.8)/(25x0.8)-0.75 =1-0.75 =0.25

7.82÷0.75=10.426666667.82÷0.75是循环小数
