1.7×0.9+1.2÷0.3-0.2=48.8 这个括号怎么加才能使算式成立啊!1.7×0.9+1.2÷0.3-0.2=48.8 2.7×0.9+1.2÷0.3-0.2=18.3 3.7×0.9+1.2÷0.3-0.2=75 4.7×0.9+1.2÷0.3-0.2=47.6 共有四个,
在下面算式中添上括号,使等式成立7×0.9+1.2÷0.3-0.2=48.87×0.9+1.2÷0.3-0.2=1477×0.9+1.2÷0.3-0.2=757×0.9+1.2÷0.3-0.2=47.6
在下面的算式中添上括号,使等式成立.7×0.9+1.2÷0.3-0.2=48.87×0.9+1.2÷0.3-0.2=1477×0.9+1.2÷0.3-0.2=75
在下面的算式中填上括号,使等式成立.7×0.9+1.2÷0.3-0.2=48.87×0.9+1.2÷0.3-0.2=1477×0.9+1.2÷0.3-0.2=75
一.添括号,使算式成立.7×0.9+1.2÷0.3-0.2=25
给算式添括号.1)7×0.9+1.2÷0.3-0.2=48.8 2)7×0.9+1.2÷0.3-0.2=147 3)7×0.9+1.2÷0.3-0.2=754) 7×0.9+1.2÷0.3-0.2=47.6
7×1.2+0.9÷0.3-0.2=48.8 添上小括号使等式成立谁知道呀
(0.8x+0.9)÷0.5=(x+5)÷2+(0.3x-0.2)÷0.3
简算:0.1×0.2×0.4×+0.2×0.4×0.8+0.3×0.6×1.2分之0.1×0.3×0.9×+0.2×0.6×1.8+0.3×0.9×2.7=
(0.1×0.2×0.4+0.2×0.4×0.8+0.3×0.6×1.2)分之(0.1×0.3×0.9+0.2×0.6×0.8+0.3×0.9×2.7)=
7*0.9+1.2/0.3-0.2=75 仲么添括号使等式成立?
7*0.9+1.2/0.3-0.2=48.8和24.8填括号使等式成立
(0.1*0.3*0.9+0.2*0.6*1.8+0.3*0.9*2.9)除以(0.1*0.2*0.4+0.2*0.4*0.8+0.3*0.6*1.2)
(0.1*0.3*0.9+0.2*0.6*1.8+0.3*0.9*2.9)除以(0.1*0.2*0.4+0.2*0.4*0.8+0.3*0.6*1.2)
0.1+0.2+0.3+0.4+.+0.9=( )
(0.8x+0.9)÷0.5=(x+5)÷2+(0.3x-0.2)÷0.3运用去分母的方法解方程,
0.4y+0.9-0.3分之0.3+0.2y=1
0.4y+0.9/0.5-0.3+0.2y/0.3=1
