What is Rule of Three Inverse

The rule of three inverse is a mathematical method used to solve inverse proportion problems where the product of two pairs of values is equal. If you know three values in an inverse proportion (a × b = c × x), you can find the fourth value (x) using the formula x = (a × b) / c. This method is used when one quantity increases as another decreases proportionally.
