Question

 (-1,5) : 2 = x :(−12)

Answer 1

\(\left(-1,5\right):2=x:\left(-12\right)\)

\(-0,75=x:\left(-12\right)\)

\(x.\left(-12\right)=-0,75\)

\(x=-0,75.\left(-12\right)\)

\(\Rightarrow x=9\)

Answer 2

\(\dfrac{x}{-12}=\dfrac{-1.5}{2}\)

\(\Leftrightarrow x=\dfrac{12\cdot1.5}{2}=\dfrac{18}{2}=9\)

Answer 3

\(\Leftrightarrow x=\left(-\dfrac{3}{2}:2\right)\left(-12\right)=-\dfrac{3}{4}\left(-12\right)=9\)
