Question

express in rational form

Answer 1

let x=0.123(bar on 23)

10 x=1.23(bar on 23)

1000x=123.23(bar on 23 after decimal point)

1000x-10x=123.23(bar on 23 aftr decimal) - 1.23(bar on 23)

9990x=122

x=122/990

Answer 2

let x=0.123(bar on 23)

10 x=1.23(bar on 23)

1000x=123.23(bar on 23 after decimal point)

1000x-10x=123.23(bar on 23 aftr decimal) - 1.23(bar on 23)

9990x=122

x=122/990
