    The simplification of \[(0.\overline{63}+0.\overline{37}+0.\overline{80})\] yields the result

    A)  \[1.\overline{80}\]                     

    B)  \[1.\overline{81}\]

    C)  \[1.\overline{79}\]                                 

    D)  1.80

    Correct Answer: B

    Solution :

    Expression \[=0.\overline{63}+0.\overline{37}+0.\overline{80}\] \[=\frac{63}{99}+\frac{37}{99}+\frac{80}{99}\] \[=\frac{63+37+80}{99}=\frac{180}{99}\] \[=1\frac{81}{99}=1.\overline{81}\]
