[tex]\bf \begin{array}{ccll}
liters&kgs\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
5&7.5\\
2&k
\end{array}\implies \cfrac{5}{2}=\cfrac{7.5}{k}\implies k=\cfrac{2\cdot 7.5}{5}[/tex]
you can do this:
5/7.5=2/x
cross multiply, and get 5x=15
x=3
Thus, the weight of a two-liter jug should equal 3kg
Hope this helps!
