[tex]\frac{20.8}{9}[/tex]

Set [tex]x[/tex] to 2.31 with 1 repeating.

[tex]x=2.31...[/tex]

Now multiply the value by 10 so we can have canceling values.

[tex]10x=23.1...[/tex]

Then we can use elimination.

[tex]10x=23.1...[/tex]

[tex]x=2.31...[/tex]

[tex]9x=20.8[/tex]

[tex]x=\frac{20.8}{9}[/tex]

Hope this helps.

頑張って!
