What is Inverse Proportion?
Inverse proportion involves multiplicative reasoning. Inverse proportion requires students to work comfortably with fractions and decimals. There are four inverse proportion statements below.
1) y is inversely proportional to x equates to y = k/x. y is inversely proportional to the square of x equates to y = k/x2. 2) y is inversely proportional to the cube of x equates to y = k/x3. 3) y varies inversely with the square root of x equates to y = k/√x. 4) 'y varies inversely with the square root of x' is the same as the statement 'y is inversely proportional to the square root of x'.
The tables below show y is inversely proportional to x. We find the constant k by multiplying x with y such that xy = k.
How to do Inverse Proportion
The inverse proportion question below states that s is inversely proportional to the square root of T.
The diagram below shows inverse proportion when mapped on a graph. As the independent variable increases the dependent variable decreases inversely.
