Inversely Proportional Calculator

What is an Inversely Proportional Calculator?

An 'Inversely Proportional Calculator' is an online tool that finds the inversely proportionate value for the given value of one variable and constant. Cuemath's 'Inversely Proportional Calculator' helps you to find the inversely proportionate value for the given value of one variable and constant within a few seconds.

How to Use Inversely Proportional Calculator?

Follow the given steps to use the calculator:

  • Step 1: Enter the value for one of the variables and the constant to find the other variable.
  • Step 2: Click on "Solve" to know the other variable.
  • Step 3: Click on "Reset" to enter the new set of values.

How to find the Inversely Proportional?

When two quantities are related to each other inversely, i.e., when an increase in one quantity brings a decrease in the other and vice versa then they are said to be inversely proportional. Inverse proportion formulas help in establishing a relationship between two inversely proportional quantities.

Let x and y be two quantities.

Then y is said to be inversely proportional to x, and is written mathematically as:

y ∝ 1/x

y = c/x

Where, x and y are the variables and c, Constant value between them.

Let us understand more about this with the help of the below-solved example.

Solved Example: 

Find the value of y for the value of the variable x = 20 and constant c = 5


The given value of x is 20 and c is 5

y ∝ 1 / x

= (constant, c) / x 

= 5 / 20

= 0.25

Therefore the inverse proportion value of x, y = 0.25.

Now, try the calculator to find the value of x, when y is inversely proportional to x

a)  Variable y = 4 and Constant c = 60

b)  Variable y = 5 and Constant c = 30
