A situation represents a proportional relationship if you can write equivalent ratios of related quantities in that situation.
<u>Step-by-step explanation</u>:
The proportional relationships can be represented in many ways:
i) One way is considering a straight line graph passing through the origin.
ii) A verbal description describing the directly proportional relationship between two quantities.
iii) An equation y=kx, here k= constant of proportionality.
For example:
1/2 and 5/10 have a proportional relationship
Both of them are same.
The proportional relationship can help in dealing with the real life problems. Some of them are scaling a diagram, adjusting a recipe and finding increase/decrease in percentage.
