What does a proportion mean?

It is the equality between two or more ratios derived from measurements extracted from quantities. When two ratios have the same result, we say they are proportional.

To make the proportionality have to perform the rule of 3 then we have that will be:

[tex]x=(36*380)/120[/tex]

[tex]x=114[/tex]
