Answer:

[tex]0.\bar2=\frac{2}{9}[/tex]

Step-by-step explanation:

We want to find the rational number which is equal to [tex]0.\bar2[/tex].

Let [tex]y=0.\bar2[/tex]....eqn(1)

Multiply both sides by 10

[tex]10y=2.\bar2[/tex].....eqn (2)

Subtract eqn (1) from eqn (2)

[tex]10y-y=2.\bar2-0.\bar2[/tex]

[tex]\implies 9y=2[/tex]

Divide both sides by 9.

[tex]\implies y=\frac{2}{9}[/tex]
