The ratio of two numbers, $a$ and $b$, is their quotient $\frac ab$. This ratio can be expressed as $\frac ab$, $a:b$, $a$ to $b$, or simply as a decimal.


Two ratios are considered proportional to each other (more specifically, directly proportional) if the two ratios equal each other. In other words, $\tfrac{a}{b} = \tfrac{c}{d}$.
