    B)  \[\frac{-2}{3}\]-and \[\frac{8}{12}\]

    C)  \[\frac{12}{15}\] and \[\frac{10}{18}\]   

    D)  \[\frac{27}{54}\] and \[\frac{3}{2}\]

    Correct Answer: A

    Solution :

    \[\frac{1}{4}\] can be written as \[\frac{1\times 4}{4\times 4}=\frac{4\times (-1)}{16\times (-1)}=\frac{-4}{-16}\] \[\therefore \]  \[\frac{1}{4}\]and \[\frac{-4}{-16}\] are equivalent rational numbers.
