    Find the quotient of the algebraic terms in \[\frac{36{{x}^{3}}{{y}^{2}}z}{-9{{x}^{2}}\,{{y}^{2}}z}\].

    A)  \[4x\]                                  

    B)  \[4x{{y}^{2}}z\]               

    C)         \[-4x\]                

    D)         \[4{{x}^{3}}{{y}^{2}}z\]

    Correct Answer: C

    Solution :

    \[\frac{36\,{{x}^{3}}{{y}^{2}}z}{-9{{x}^{2}}{{y}^{2}}z}=\frac{36}{-9}\left( \frac{{{x}^{3}}}{{{x}^{2}}} \right)\,\,\left( \frac{{{y}^{2}}}{{{y}^{2}}} \right)\,\,\left( \frac{z}{z} \right)=-4x\]
