Exploring Proportional Relationships in 7th Grade Math

What is a proportional relationship?

• A relationship where one variable is always greater than the other.

• A relationship where the ratio between two variables is constant.

• A relationship where the difference between two variables is constant.

• A relationship where the sum of two variables is constant.

In the pancake recipe example, how many cups of milk are needed for 3 eggs?

• 12 cups

• 9 cups

• 6 cups

• 3 cups

What is the ratio of eggs to cups of milk in the pancake recipe for 1 egg?

• 2:3

• 1:1

• 1:2

• 2:1

How do you test if a relationship is proportional?

• By checking if the ratio between the variables is equivalent.

• By checking if the difference between the variables is the same.

• By checking if the sum of the variables is the same.

• By checking if one variable is always greater than the other.

In the pancake recipe, if you use 12 eggs, how many cups of milk do you need?

• 18 cups

• 12 cups

• 30 cups

• 24 cups

In the cake cost example, what is the cost for 20 servings?

• $30

• $35

• $20

• $25

Why is the cake cost example not a proportional relationship?

• Because the cost increases by a fixed amount.

• Because the ratio of servings to cost is not constant.

• Because the number of servings is always greater than the cost.

• Because the cost decreases as the number of servings increases.

What is the constant of proportionality in the pancake recipe example?

• 1

• 2

• 3

• 4

Which of the following is true for a proportional relationship?

• The sum of the variables is always the same.

• One variable is always a constant times the other variable.

• The ratio between the variables changes.

• The difference between the variables is always the same.

What is another way to think about proportional relationships?

• One variable is always greater than the other.

• The difference between the variables is always the same.

• One variable is always a constant times the other variable.

• The sum of the variables is always the same.
