    Evaluate p+q given \[P=\left( -6\frac{1}{6} \right)\]and\[q=\left( -8\frac{1}{8} \right)\].

    A)  \[\left( -14\frac{13}{24} \right)\]             

    B)  \[\left( -14\frac{7}{24} \right)\]

    C)  \[\left( -3\frac{8}{18} \right)\]                 

    D)  \[\left( 13\frac{19}{24} \right)\]

    Correct Answer: B

    Solution :

    (b) Given p+q\[=\left( -6\frac{1}{6} \right)+\left( -8\frac{1}{8} \right)\] \[=\frac{-37}{6}-\frac{65}{8}\] \[=\frac{-148-125}{24}\] \[=\frac{-343}{24}=-14\frac{7}{24}\]
