    The sum of two rational numbers is \[-5\]. If one of the numbers is \[\frac{-3}{5},\] what is the other number?

    A)  \[-4\frac{2}{5}\]              

    B)                         \[4\frac{8}{5}\]               

    C)                         \[\frac{-6}{5}\]                                

    D)                         \[4\frac{6}{5}\]

    Correct Answer: A

    Solution :

                    Let \[x\] be the required number.           So,  \[x+\left( \frac{-3}{5} \right)=-5\] \[x=-5+\frac{3}{5}=\frac{-25+3}{5}=\frac{-22}{5}=-4\frac{2}{5}\]
