Simplify the following expression.
​$$0.\bar{12}- 0.\bar6 + 0.\bar3$$​​

Correct option is D

Given:

​$$0.\bar{12 }- 0.\bar6 + 0.\bar3$$ 

Concept Used:

$$0.ab\bar c= \frac{abc - ab }{900}$$  

​$$0.\bar12 - 0.\bar6 + 0.\bar3$$ 

$$= \frac{12}{99} - \frac{6}{9} + \frac{3}{9}$$  

= $$\frac{12 - 66 + 33}{99}$$ 

= $$\frac{-21}{99}$$ 

= $$\frac{-7}{33}$$​​
