[tex]\bf \dfrac{x}{5} = \dfrac{10}{25}\implies 25\cdot x = 5\cdot 10\implies 25x=50\:\Big|:25\implies \boxed{\bf x = 2}[/tex]
[tex]\bf \dfrac{2x}{7} = \dfrac{4}{28}\implies 28\cdot 2x =4\cdot 7\implies 56x=28\:\Big|:56\implies \boxed{\bf x = \dfrac{1}{2}}[/tex]
[tex]\bf \dfrac{3}{x} = \dfrac{9}{12}\implies 9\cdot x =3\cdot 12\implies 9x=36\:\Big|:9\implies \boxed{\bf x = 4}[/tex]
[tex]\bf \dfrac{4}{16} = \dfrac{8}{x}\implies 4\cdot x =8\cdot16\implies 4x=128\:\Big|:4\implies \boxed{\bf x = 32}[/tex]
[tex]\bf \dfrac{5}{30} = \dfrac{x}{6}\implies x\cdot 30 =5\cdot6 \implies 30x=30\:\Big|:30\implies \boxed{\bf x = 1}[/tex]
