6.8%6.8×0.55+8.5的脱式计算

6.8-6.8×0.55+8.5 =6.8-3.74+8.5 =3.06+8.5 =11.56

(6.8-6.8x0.55)÷8.5 =6.8x(1-0.55)÷8.5 =6.8ⅹ0.45÷8.5 =3.06÷8.5 =0.36

(6.8-6.8 x0.55)÷8.5简便方法 =(6.8-3.74)÷8.5 =3.06÷8.5 =0.36 不能简便

(6.8-6.8x0.55)÷8.5 =[6.8-(6.8x0.55)]÷8.5 =(6.8-3.74)÷8.5 =3.06÷8.5 =0.36

原式 =6.8×(1-0.55)÷8.5 =6.8×0.45÷8.5 =0.36 如果我的回答对你有帮助,请及时选为满意答案,谢谢~~

(6.8-6.8x0.55)÷8.5 =6.8x(1-0.55)÷8.5 =6.8x0.45÷8.5 =3.06÷8.5 =0.36

简算: 45.55-(6.82+15.55) 34.52-17.87-12.23 6.43-(1.4-0.57) 23.75-8.64-3.46 17.83-9.5-7.83-0.5 5.38+88.2-2.38+1.8 ...

(6.8-6.8*0.55)/8.5 =6.8x(1-0.55)÷8.5 =6.8x0.45x2/17(约分得) =0.4x0.9 =0.36

您好: (6.8-6.8*0.55)/8.5 =6.8*(1-0.55)÷8.5 =1.7*4*0.45÷1.7÷5 =4*0.9 =3.6 如有不明白,可以追问 如有帮助,记得采纳,谢谢 祝学习进步!
