Find out the standard forms of the rational numbers $ \frac{-28}{21} $ and $ \frac{-8}{6} $.

A rational number $\frac{p}{q}$ is said to be in the standard form if $q$ is positive, and the integers $p$ and $q$ have no common divisor other than 1.

Therefore,

Standard form of rational number $\frac{-28}{21}=\frac{-7\times4}{7\times3}=\frac{-7}{3}$.

Standard form of rational number $\frac{-8}{6}=\frac{-2\times4}{2\times3}=\frac{-4}{3}$.
