Question

express 0.99999 ... in the form of p by q

Answer 1

0. 9 bar = 0.9999.......

Let 

x = 0.9 bar
____________________

As there is only 1  number under bar, multiply by 10 

10*x =10*0.9 bar

10x = 9.9 bar
-   x = -0.9 bar [subtract x from both sides]

9x = 9 (bar will cancel)

x= 9/9

x = 1


Now,

0.9 bar in p/q  is equal to 1

0.99999... in p/q form is equal to 1
