Please someone Tell Me answer Of this ques. step by step​

Answer 1

Step-by-step explanation:

let x=0.999999...

=> 10x=9.99999...

=> 10x-x=(9.99999...)-(0.99999...)

=> 9x = 9

=> x = 1

hence, 0.9 bar (i.e x) can be represented as 1/1 in p/q form.

x= 1

hence,0.9bar can be respresented as 1/1 in rational form
