Teaching Interpreting Proportional Relationships Easily 


  • To check whether two quantities are proportional or not, always find the ratio between them. 
  • If the ratio is equal, then they are in a proportional relationship or constant of proportionality. 
  • If two quantities are proportional to each other, they are defined as y = kx. 


Here is an example to solve a problem on interpreting proportional relationships. Let’s look at the given example mentioned below to understand more about the concept.


Number of Days = x 369
Number of Articles = y 91827






Interpret the Proportional Relationship for the above table. 


Step 1: Apply the equation = y = kx. 


Step 2: To find the constant of proportionality, find the ratio between the number of days by the number of articles. 


K = y/x = 9 / 3 = 3, 18 / 6 = 3,...
