Find Constant Of Proportionality (Equations) Worksheet

When two different variables are indirectly or directly proportional to each other, their relationship can be expressed using an equation i.e y = kx or y = k/x. Here, x determines or identifies how the two variables ( x and y) are related to each other. This is known as the ‘constant of proportionality’. The value of the constant of proportionality totally depends upon the qualities of the two quantities.

 Teaching Solving Constant of Proportionality Easily 

 

  • Firstly, note down the values of the variables. For example x = 3 and y = 24. 


 

  • Then, you may use the constant of proportionality formula. The mathematical formula of constant of proportionality is y = kx or y = k/x. 


 

  • The resultant value is the constant of proportionality for the given equation. 


 

Let us look at the given example mentioned below to understand more about the constant of proportionality. 


 

Q. Q. It is given that a variable y varies proportionally with x. Find the constant of proportionality if y = 25 and x = 5. 


 

Solution: 


 

Step 1: Note down the quantities of the two variables, 

So, 

Y = 25 

X = 5 


 

Step 2: Find the constant of proportionality using the formula. 

So, 

Y = kx. 

25 = k * 5 

K = 25 / 5 = 5

Hence, the constant of proportionality is 5. 


 

Why should you use a find constant of proportionality (equations)worksheet for your students? 

 

  • Students can now easily determine the constant of proportionality in an equation using these worksheets. 


 

  • These worksheets can help your students to know more about proportions and its different types.
