Basic Concepts

Ratios, Proportions, and Rates

Making Comparisons

Ratios show the relationship between two quantities. Proportions are equations that state two ratios are equal. Rates compare quantities with different units (like miles per hour).

Solving Proportions

Use cross-multiplication to solve for missing values in proportions: \[ \frac{a}{b} = \frac{c}{d} \implies a \times d = b \times c \]

Everyday Uses

Ratios and rates are used in recipes, maps, and even sports statistics!

Examples

  • A recipe calls for 2 cups of flour for every 3 cups of sugar. What is the ratio of flour to sugar?

  • If a car travels 180 miles in 3 hours, what is its average speed in miles per hour?

In a Nutshell

Understand how to compare quantities and solve real-world problems with ratios and rates.
