Answer 2

Answer:

If you meant 0.9 without bar then its 9/10.

If you meant 0.99999.... then its also 9/10.

Step-by-step explanation:

If its 0.9 without the bar then its 9/10.

If its 0.999.... then its---

Let 0.9= x          ____(1)   (0.9 has a bar on 9)

Therefore,  10 * 0.9 = 10x  

=> 9.9 = 10x       _____(2) (9.9 has a bar on 9)

     Now we subtract (1) from (2)

 9.9-0.9 = 10x -x     (0.9 and 9.9 have a bar on 9)

     9/10 = x

Therefore ,p/q form of 0.999..... where q≠0 = 9/10

(They are both the same)
