3.9+0.1%3.9+0.1用简便方法计算怎么计算?

3.9+0.1-3.9+0.1 =(3.9-3.9)+(0.1+0.1) =0+0.2 =0.2

解: 3.8/3.9+3.9/0.1+0.1/3.9 =38/39+39+1/39 =39+(38/39+1/39) =39+1 =40

3.9+0.1-3.1+0.1用简便运算 =(3.9+0.1)-(3.1-0.1) =4-3 =1

1.9+1.99+199.1+0.3的简便计算 解: 1.9+1.99+199.1+0.3 =(1.9+0.1)+(1.99+0.01)+(199.1-0.1)+(0.3-0.01) =2+2+199+0.29 =203.29

1.9+2.9+3.9+0.3 =(1.9+0.1)+(2.9+0.1)+(3.9+0.1) =2+3+4 =9

你好: 23x0.1+2.3x9.9 =2.3x1+2.3x99 =2.3x(99+1) =2.3X100 =230 如果满意记得采纳! 求好评! (*^__^*) 嘻嘻……

=2*1.9*1.6+3.8*0.34 =3.8*(1.6+0.34) =3.8*(2-0.06) =7.6-0.229 =7.572

3.5×(1.9+2.9)÷0.3 =3.5×{[(2-0.1)+(3-0.1)]÷0.3} =(3+0.5)×{[(2+3)-(0.1+0.1)]÷0.3} =(3+0.5)×[(5-0.2)÷0.3] =(3+0.5)×(4.8÷0.3) =(3+0.5)×16 =3×16+0.5×16 =48+8 =56
