[tex]\frac{0,6}{4} = \frac{18}{x}[/tex]
[tex]0,6 = \frac{6}{10} =\frac{3}{5}[/tex] → am simplificat cu 2
⇒ [tex]\frac{\frac{3}{5}}{4} = \frac{18}{x}[/tex]
[tex]\frac{3}{5} * \frac{1}{4} = \frac{18}{x}[/tex]
[tex]\frac{3}{20} = \frac{18}{x}[/tex]
[tex]3x = 20 * 18[/tex]
[tex]x = \frac{20*18}{3}[/tex]
[tex]x = \frac{360}{3}[/tex]
[tex]\boxed{x = 120}[/tex]
