Question

Rewrite 2.31 (1 repeating) as a simplified fraction.

Answer 1

`(20.8)/(9)`

Set
`x` to 2.31 with 1 repeating.

`x=2.31...`

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

`10x=23.1...`

Then we can use elimination.

`10x=23.1...`

`x=2.31...`

`9x=20.8`

`x=(20.8)/(9)`

Hope this helps.

頑張って!
