This page delves deeper into practical applications of ratios and rates, focusing on more complex calculations involving the International Space Station's orbital speed and subway car velocity measurements.

Example: The page works through calculating the International Space Station's speed in miles per second using a ratio table.

Vocabulary: Complex fraction is defined as a fraction that contains fractions within it.

Highlight: The page demonstrates how to interpret and analyze speed graphs, comparing different representations of the same speed (0.5 miles per minute).

This page focuses on practical applications of ratios and rates in everyday scenarios, including paint mixing proportions and price comparison problems.

Example: A detailed paint mixing problem shows how to calculate the required amounts of yellow and blue paint to make 15 cups of green paint using ratio relationships.

Highlight: The page concludes with a practical price comparison problem between different sizes of cereal boxes, demonstrating how to determine the better value using unit rates.

Example: A price comparison between a 16 oz box of cereal for $5.49 and a 20 oz box for$5.99 shows how to use unit rates to determine the better value.

This page introduces the fundamental concepts of ratios and rates in mathematics. A ratio compares two quantities using division where both quantities share the same units. The page demonstrates three different ways to write ratios: using "to" (3 to 4), using a colon (3:4), or as a fraction $3/4$.

Definition: A rate is a comparison of two quantities with different units, typically expressing speed or other measurements where units differ.

Example: A practical example shows how to find the ratio of males to females in a subway car (45:60 simplified to 3:4) and calculate the car's speed (0.5 miles per minute).

Vocabulary: Unit rate refers to a rate with 1 in the denominator, such as 30 miles/hour.

Highlight: The page includes a detailed example of using ratio tables to find unit rates in the context of artificial turf pricing, demonstrating how to calculate the cost per square foot.
