Answer 1

\(2,25:\dfrac{-6}{25}=\dfrac{9}{4}:\dfrac{-6}{25}\\ =-\dfrac{9}{4}\cdot\dfrac{25}{6}=-\dfrac{3}{4}\cdot\dfrac{25}{2}\\ =-\dfrac{75}{8}\)

Answer 2

[FAIRY TAIL]

\(2.25:\dfrac{-6}{25}\) = \(\dfrac{9}{4}:\dfrac{-6}{25}=\dfrac{9}{4}.\dfrac{25}{-6}=\dfrac{3}{4}.\dfrac{25}{-2}=\dfrac{75}{-8}=\dfrac{-75}{8}\)
