Key Concepts
Property A ratio is a comparison of two numbers by division. It can be written with the word 'to' (3 to 4), as a fraction ($\frac{3}{4}$), as a decimal (0.75), or with a colon (3:4).
Examples In a class with 12 girls and 16 boys, the ratio of girls to boys is $\frac{12}{16} = \frac{3}{4}$. A bag has 6 red marbles and 8 blue ones; the ratio of red to blue is $\frac{6}{8} = \frac{3}{4}$. The ratio 5 to 2 can also be written as $5:2$ or as the fraction $\frac{5}{2}$.
Explanation Think of a ratio as a recipe for comparing things! It shows how much of one item you have for every certain amount of another. It helps simplify relationships, like comparing 12 girls to 16 boys by just saying it’s a 3 to 4 ratio.
