5个0.2怎么等于3

(0.2+0.2)÷0.2+0.2÷0.2=3

[(0.2+0.2)/0.2]+0.2/0.2=3

5(0.2+x)=3解:0.2+x=3÷5 0.2+x=0.6 x=0.6-0.2 x=0.4

0.2(+ )0.2( -)0.2(- )0.2( *)0.2=0.

(0.2+0.2)/0.2+0.2/0.2=3 0.2/0.2/0.2+0.2-0.2=5 (0.2/0.2+0.2+0.2)/0.2=7 0.2/0.2/0.2+0.2/0.2=6

(0.2+0.2)÷0.2+(0.2-0.2)=2(0.2+0.2)÷0.2+0.2÷0.2=3(0.2+0.2+0.2+0.2)÷0.2=40.2÷0.2÷0.2+0.2-0.2=5

(0.2-0.2)÷0.2*0.2*0.2=0 (0.2+0.2)÷0.2-0.2÷0.2=1 (0.2+0.2)÷0.2-(0.2-0.2)=2 (0.2+0.2)÷0.2+0.2÷0.2=3

(0.2/0.2+0.2)/(0.2+0.2)=3

0.2÷0.2=11+0.2=1.21.2+0.2=1.41.4÷0.2=7综合算式为:(0.2÷0.2+0.2+0.2)÷0.2=7有不明白的地方再问哟,祝你学习进步,更上一层楼! (*^__^*)

根据5*0.2等于三分之一乘以三改为两个比例是:5:3分之1=3:0.23分之1:0.2=5:3
