Key Concepts
Property A ratio is a type of quotient used to compare two numerical quantities. The ratio of $a$ to $b$ is written $\frac{a}{b}$. A ratio can be expressed as a decimal instead of a common fraction.
Examples In a class with 15 boys and 12 girls, the ratio of boys to girls is $\frac{15}{12}$, which simplifies to $\frac{5}{4}$.
A recipe calls for 2 cups of sugar for every 5 cups of flour. The ratio of sugar to flour is $\frac{2}{5}$.
