Question
The sum of two rational numbers is -4. If one of them is \( \frac{-13}{25} \), then the other is:
The correct answer is
\( \frac{-87}{25} \)
Let the other number be \( x \).
Given: \[ x + \frac{-13}{25} = -4 \] Rearranging: \[ x = -4 + \frac{13}{25} \] Express -4 with denominator 25: \[ x = \frac{-100}{25} + \frac{13}{25} \] \[ x = \frac{-87}{25} \] Thus, the other rational number is \( \frac{-87}{25} \).
