Answer 2

Hey

Lets take another example.

Q. Express 0.123 bar on number line.
Ans. Let X = 0.123(bar on 23)
10X = 1.23(bar on 23)
10X = 1+0.23(bar on 23)
10X = 1+23/99
10X = 99+23/99
10X = 122/99
x = 122/99*10
x = 122/990

Sorry. for not solving your question but you will understand from this.
Hope this helps
