Variation and proportion are defined to be the relationship between two or more variables with regard to a constant of proportionality.

The traditional notation for direct proportionality is xy or, if using regular equality notation, x=ky.

Here, k denotes the constant of proportionality.

Similarly, the traditional notation for inverse proportionality is x1/y or, with regular equality, x=k/y.

For direct proportionality, to find the value of an unknown x or y, you may use the formula: y1/x1=y2/x2

Similarly, for inverse proportion it would be: x1/y1=y2/x2
