\(6:\left(-27\right)=\left(-6\dfrac{1}{2}\right):29\dfrac{1}{4}\)
\(\Leftrightarrow\dfrac{6}{-6\dfrac{1}{2}}=\dfrac{29\dfrac{1}{4}}{-27};\dfrac{6}{29\dfrac{1}{4}}=\dfrac{-6\dfrac{1}{2}}{-27}\)
\(\dfrac{-6\dfrac{1}{2}}{6}=\dfrac{-27}{29\dfrac{1}{4}};\dfrac{29\dfrac{1}{4}}{6}=\dfrac{-27}{-6\dfrac{1}{2}}\)
