3.24÷0.36的验算

3.24÷0.36=9 验算: 0.36 × 9 = 3.24 竖式见图:

3.24÷3÷0.12 =1.08÷0.12 =1.08÷3÷0.04 =0.36÷0.04 =9

最后等于9无法用竖式计算列出来

=3.24×(1/0.36+1/0.64) =3.24×[1/(0.36×0.64)] =3.24÷0.36÷0.64 =14.0625

3.24除0.36加3.24除以0.14简便计算 3.24除0.36加3.24除以0.14 =3.24÷0.36+3.24÷0.14 =9+ 3.24÷0.14,结果不是有限小数 不能写成3.24÷(0.36+0.14)

3.24÷2.4=1.35

24.3-24.3÷4.5 =24.3-5.4 =18.9
