Understanding Ratio Relationships and Comparisons

The video tutorial covers grade six module one lesson 12 on multiple ratio relationships. It explores how to determine if sets of ratios belong to the same relationship using graphs, tables, and double number lines. The lesson includes practical examples comparing ratios in stores selling apples, analyzing smoothie ratios, and tackling challenges in comparing marble ratios. The focus is on identifying constants for direct comparison and understanding when ratio relationships differ.

What is the primary focus of the lesson on ratio relationships?

• Understanding how to solve equations

• Learning about historical events

• Determining if sets of ratios belong to the same relationship

• Exploring different types of graphs

In the comparison of apple prices, what is the key factor in determining if the ratio relationships are the same?

• The color of the apples

• The store location

• The price for the same weight of apples

• The type of apples sold

How does Store A's pricing for six pounds of apples compare to Store B's?

• Store A does not sell apples

• Store A and Store B charge the same

• Store A charges more than Store B

• Store A charges less than Store B

In the smoothie recipe analysis, what is the constant factor used to compare the ratios?

• Number of cups of strawberries

• Number of bananas

• Price of the smoothie

• Type of fruit used

What is the difference in the number of cups of strawberries used by Store A and Store B for two bananas?

• Store A uses 3 cups, Store B uses 2 cups

• Store A uses 2 cups, Store B uses 3 cups

• Store A uses 4 cups, Store B uses 3 cups

• Store A uses 3 cups, Store B uses 4 cups

What makes the marble ratio comparison challenging?

• The ratios do not have a common comparison point

• The marbles are different colors

• The marbles are different sizes

• The marbles are not counted

How is the ratio of red to blue marbles manipulated to find a common comparison point?

• By removing some marbles

• By dividing the values to find a common factor

• By changing the color of marbles

• By adding more marbles

What is the result of dividing 28 by 3 in the marble ratio comparison?

• 8

• 10

• 9 and a third

• 9

What is the key takeaway from the lesson on ratio relationships?

• Ratios are not useful in real life

• Ratios can be compared using a common value

• Ratios are always the same

• Ratios are only used in math class

What should you do if you cannot find a common value in ratio comparisons?

• Give up on the comparison

• Assume the ratios are the same

• Try to manipulate the values to find a common factor

• Ignore the ratios
