Proportional Relationships in a Table (Part 1)

The video tutorial explains proportional relationships, using a fruit punch recipe as an example. It describes how to determine if two ratios are proportional by converting them to decimals or by checking if their cross products are equal. Both methods confirm the equality of the ratios 2/3 and 4/6.

What is a proportional relationship?

• A relationship between two different ratios

• A relationship between two equal ratios

• A relationship between two numbers

• A relationship between two variables

In the fruit punch recipe example, how many cups of grape juice are needed if you use 4 cups of apple juice?

• 3 cups

• 8 cups

• 6 cups

• 5 cups

How can you determine if two ratios are proportional using decimals?

• By adding the ratios

• By subtracting the ratios

• By multiplying the ratios

• By converting the ratios to decimals and comparing them

What is the decimal equivalent of the ratio 2/3?

• 0.66

• 0.5

• 0.75

• 0.33

What is another method to check if two ratios are proportional?

• By dividing the numerators

• By subtracting the denominators

• By comparing the cross products

• By adding the numerators
