The Classical Exmple is C = pi d ; The circle circumference and 'd' the diameter. 'pi' is the constant of proportion.
However if given a set of data , that is directly proportional , then we say
y is directly proportional to 'x'
We now equate this by inserting a constant of proportion(k)
Then
Hence
y = kx
Then k = y/x
This is how 'pi' was found.
e.g.
C = 6.2831....
d = 2
Hence
k(pi) = 6.2831... / 2 = 3.141592....
Other sonstants of proportion are
y is inversely proportional to the square of 'x'
Hence
y = k X 1/x^(2)
k = yx^(2)

Hope that helps!!!!
There cannot be a "proportion of something": proportion is a relationship between two things, and how you solve it depends on whether they (or their transformations) are in direct proportion or inverse proportion.

An equation that states that two ratios are equal is a proportion.

Set up a proportion equation.
a proportion is an equation. a / b = c / d cross multiply: ad = bc then solve
To solve a proportion, you cross multiply. For example, if this was the proportion: 2/4 = 3/x, you would multiply 2 with x and 4 with 3. The products will be used in your next equation. In this case, your next equation is 2x = 12. Now you want to isolate x, so divide by two for both sides. Your answer will be x = 6.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is what?

It depends on the equation that is being solved.
The quadratic formula can be used to solve an equation only if the highest degree in the equation is 2.

It is used to solve quadratic equations that cannot be factored. Usually you would factor a quadratic equation, identify the critical values and solve, but when you cannot factor you utilize the quadratic equation.

A percent proportion is related to an equation because they are both used to indicate part of another whole. Equations are complex forms of fractions, sequence and they express logic.
