Answer

a. 5 ### b. -9 ### c. -1 ### d. 1 ### e. Undefined ### f. 0 Explanation 1. Evaluate \frac{-5}{-1} Divide -5 by -1. Result is positive, so \frac{-5}{-1} = 5. 2. Evaluate \frac{9}{-1} Divide 9 by -1. Result is negative, so \frac{9}{-1} = -9. 3. Evaluate \frac{120}{-120} Divide 120 by -120. Result is negative, so \frac{120}{-120} = -1. 4. Evaluate \frac{-15}{-15} Divide -15 by -15. Result is positive, so \frac{-15}{-15} = 1. 5. Evaluate \frac{8}{0} Division by zero is undefined. 6. Evaluate \frac{0}{-7} Divide 0 by -7. Result is 0, so \frac{0}{-7} = 0.

Explanation

1. Evaluate $\frac{-5}{-1}$<br /> Divide $-5$ by $-1$. Result is positive, so $\frac{-5}{-1} = 5$.<br /><br />2. Evaluate $\frac{9}{-1}$<br /> Divide $9$ by $-1$. Result is negative, so $\frac{9}{-1} = -9$.<br /><br />3. Evaluate $\frac{120}{-120}$<br /> Divide $120$ by $-120$. Result is negative, so $\frac{120}{-120} = -1$.<br /><br />4. Evaluate $\frac{-15}{-15}$<br /> Divide $-15$ by $-15$. Result is positive, so $\frac{-15}{-15} = 1$.<br /><br />5. Evaluate $\frac{8}{0}$<br /> Division by zero is undefined.<br /><br />6. Evaluate $\frac{0}{-7}$<br /> Divide $0$ by $-7$. Result is $0$, so $\frac{0}{-7} = 0$.
