Spiral Review #21 6.PFA.1 Proportional Reasoning

Front

What is proportional reasoning?

Back

Proportional reasoning involves understanding the relationship between quantities that are in proportion, meaning they maintain a constant ratio.

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities where one of the quantities is expressed as a quantity of one. For example, 15 to 1 means 15 units of one quantity for every 1 unit of another.

Front

What does the inequality x < 9 mean?

Back

It means that x is any number that is less than 9.

Front

Which graph represents a proportional relationship?

Back

A graph that passes through the origin (0,0) and has a straight line indicates a proportional relationship.

Front

What is a non-proportional relationship?

Back

A non-proportional relationship does not maintain a constant ratio between two quantities, often represented by a graph that does not pass through the origin.

Front

If the unit rate is 15 to 1, what does this imply?

Back

It implies that for every 1 unit of the second quantity, there are 15 units of the first quantity.

Front

How can you identify a non-proportional graph?

Back

A non-proportional graph will not have a straight line through the origin and may curve or have a different slope.

Front

What are two numbers that satisfy the inequality x < 8?

Back

Examples include 0.8 and 5.9, as both are less than 8.

Front

What does the inequality 3 > b indicate?

Back

It indicates that b is any number that is less than 3.

Front

How do you solve for x in the inequality x < 9?

Back

You identify numbers that are less than 9, such as 8, 7, or any negative number.
