# Work With Rational Numbers

- Show that $-\left(\frac{3}{4}\right)=\frac{-3}{4}=\frac{3}{-4}$.
- Explain why for any integers
*p*and*q*, where*q*is not 0, $-\left(\frac{p}{q}\right)=\frac{-p}{q}=\frac{p}{-q}$

## Hint:

First show that $-\left(\frac{p}{q}\right)=\frac{-p}{q}$, and then show that $\frac{-p}{q}=\frac{p}{-q}$.
