Ratio

The ratio of two numbers $r$ and $s$ is written $r/s$, where $r$ is the Numerator and $s$ is the Denominator. The ratio of $r$ to $s$ is equivalent to the Quotient $r/s$. Betting Odds written as $r:s$ correspond to $s/(r+s)$. A number which can be expressed as a ratio of Integers is called a Rational Number.
