What is the rule of three?
The rule is three is a simple calculation that allows one to calculate something in three steps. This is a common method of calculating simple formulas. The principle behind it is quite simple: You must do the same on both sides in order to reach your desired result.
Direct Rule of Three
If one magnitude is greater, the other also increases in the same proportion.
a / b = c / d
It is possible to calculate a, b and c. To calculate d:
d = c * b / a

In the same proportion, if one magnitude is greater, the other one will decrease.
It is possible to calculate d by using the following formulae: a, b and c. To calculate d:
