    The product of two rational numbers is \[\frac{-9}{16}.\] If one of the numbers is \[\frac{-4}{3},\] then the other number is ____.          

    A)  \[\frac{36}{48}\]                               

    B)  \[\frac{25}{64}\]                   

    C)                     \[\frac{27}{49}\]                   

    D)         \[\frac{27}{64}\]                   

    Correct Answer: D

    Solution :

    Let the other number be x. Then, \[x\times \left( \frac{-4}{3} \right)=\frac{-9}{16}\] \[\Rightarrow \]  \[x=\frac{-9}{16}\times \left( \frac{3}{-4} \right)\Rightarrow x=\frac{27}{64}\]
