Here is ur answer...
Let x= 0.666...or 0.6 bar. Then,
x = 0.6666... (Equation i )
= 10x = 6.666... (Equation ii )
On subtracting eqn i from eqn ii , we get
= 10x - x = 6.666... - 0.666...
= 9x = 6
= x = 6/9
= x = 2/3 Ans.
So, 0.6 bar = 2/3, which is in the form of p/q where q is not equal to 0.
Hope it helps u!
