What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together. It is expressed as a quantity per one unit of another quantity.

Front

How do you find the unit rate from a given quantity?

Back

To find the unit rate, divide the total quantity by the number of units. For example, if Johnny read 300 words in 6 minutes, the unit rate is 300 ÷ 6 = 50 words per minute.

Front

What does it mean for two ratios to be proportional?

Back

Front

How do you solve for the cost of one item when given the total cost?

Back

To find the cost of one item, divide the total cost by the number of items. For example, if Sally bought 3 candy bars for $18, the cost per candy bar is 18 ÷ 3 = $6.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is less than, greater than, less than or equal to, or greater than or equal to the other.

Front

How do you represent an inequality graphically?

Back

Front

What is the difference between a ratio and a rate?

Back

A ratio is a comparison of two quantities, while a rate is a specific type of ratio that compares two quantities with different units, such as speed (miles per hour) or price (cost per item).

Front

How do you determine if a graph represents a specific inequality?

Back

Front

What is the formula for calculating unit rate?

Back

The formula for calculating unit rate is: Unit Rate = Total Quantity ÷ Number of Units.

Front

What does it mean for a ratio to be equivalent?

Back

Two ratios are equivalent if they represent the same relationship between quantities, meaning they can be simplified to the same fraction.
