3.6 除0.25的简便计算

1. 把0.25化为分数来进行简便运算,2. 利用4x0.25=1来进行简便运算.1. 把0.25化为分数来进行简便运算3.6*0.25 =3.6*1/4 =0.9,2. 利用4x0.25=1来进行简便运算3.6*0.25 =(4-0.4)*0.25 =4*0.25-0.4*0.25 =1-0.1 =0.9

3.6÷0.25 =3.6÷(1/4) =3.6*4 =14.4

除以3.6/0.25 =3.6/(1/4) =3.6*4 =14.4

把除法换作乘法,0.25=1/4,所以3.6÷0.25=3.6÷(1/4)=3.6X4=14.4

除以3.6/0.25 =3.6/(1/4) =3.6*4 =14.4

3.6乘0.25=0.9*(4*0.25)=0.9*1=0.9

3.6x0.25=0.9x4x0.25=0.9x(4x0.25)=0.9x1=0.9

3.6÷0.25=3.6*4=14.4

3.6X0.25=36/10x1/4=0.9

4.32除以3.6除以0.25的简便运算=4.32÷0.9÷4x4=(4.32÷0.9)x(4÷4)=4.8x1=4.8
