Proust's law of constant proportions states that a given chemical compound always contains its component elements in fixed ratio (by weight). The ratio does not depend on its source and method of preparation.
proportion
Two variables, X and Y, are said to be in direct proportion if X/Y is a constant. Equivalently, Y = cX for some constant c.
It is the constant of proportionality.

Weber's Law"Ernst Weber noted that for people to really perceive a difference, the stimuli must differ by a constant "proportion" not a constant "amount."

The state of being in proportion.
x and y are in direct proportion if there is some positive constant c such that y = cx

The Circumference of a circle is directly proportional to the diameter. The constant of proportion is 'pi = 3.141592....'. Another one is force is directly proportional to mass. The constyant of proportion is acceleration.
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
Yes.
Direct Proportion
This was an idea of John Dalton.
