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 single unit. For example, if 1¼ cups of milk make 15 brownies, the unit rate is 12 brownies per cup.

Front

How do you determine if two quantities are in a proportional relationship?

Back

Two quantities are in a proportional relationship if they can be expressed as equivalent ratios. This means that the ratio of one quantity to another remains constant.

Front

How do you find the missing value in a proportional relationship?

Back

To find the missing value in a proportional relationship, set up a proportion equation and cross-multiply to solve for the unknown.

Front

What is the constant rate in a proportional relationship?

Back

The constant rate is the value that relates the two quantities in a proportional relationship, often represented as k in the equation y = kx.

Front

How do you calculate a unit rate from a given quantity?

Back

To calculate a unit rate, divide the total quantity by the number of units. For example, if you have 15 brownies made with 1¼ cups of milk, divide 15 by 1.25 to find the unit rate.

Front

What does it mean for a deal to be better based on unit rates?

Back

A better deal is determined by comparing unit rates; the option with the lower unit rate offers more value for the same quantity.

Front

What is the simplest form of a ratio?

Back

The simplest form of a ratio is when the numbers are reduced to their smallest whole number values while maintaining the same relationship.

Front

How do you express a ratio in simplest form?

Back

To express a ratio in simplest form, divide both terms of the ratio by their greatest common divisor (GCD).

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where their ratio remains constant.
