Real-World Applications of Ratios and Rates

The video tutorial covers representing ratios using tables and patterns, explaining how to identify and extend patterns with colored squares. It introduces double number lines for visualizing ratios and demonstrates using tables to find equivalent ratios. The lesson concludes with a summary and homework instructions, emphasizing the importance of understanding ratios in different contexts.

What is a limitation of using a double number line for large numbers?

• It becomes too long and impractical

• It requires complex calculations

• It is difficult to visualize

• It cannot represent fractions

How do you fill in a table to show equivalent ratios?

• By adding the same number to each part of the ratio

• By multiplying both parts of the ratio by the same number

• By dividing both parts of the ratio by the same number

• By subtracting the same number from each part of the ratio

What is the advantage of using a table over a double number line?

• Tables are more visually appealing

• Tables can handle larger numbers more easily

• Tables require less mathematical knowledge

• Tables are faster to create
