For direct proportions where A relates to B as C relates to X, the cross-multiplication formula is X = (B × C) / A. For inverse proportions where A relates to B as C relates to X inversely, the formula is X = (A × B) / C.
In a direct proportion, when one variable increases, the other increases at the same rate. In an inverse proportion, when one variable increases, the other decreases proportionately.
