Answer 4

\(\dfrac{8}{-12}\) = \(\dfrac{8:4}{-12:4}\)= \(\dfrac{-2}{3}\)

\(\dfrac{400}{700}\) = \(\dfrac{400:100}{700:100}\) = \(\dfrac{4}{7}\)

\(\dfrac{-10}{6}\) = \(\dfrac{-10:2}{6:2}\)= \(\dfrac{-5}{3}\)

\(\dfrac{-35}{-105}\) = \(\dfrac{35}{105}\) = \(\dfrac{35:35}{105:35}\)= \(\dfrac{1}{3}\)
