Unit Rate, Rate Tables & Solving Proportions Practice

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 single unit. For example, if you buy 3 pounds of granola for $3.75, the unit rate is the cost per pound.

How do you calculate the unit rate?

Back

To calculate the unit rate, divide the total amount by the number of units. For example, if you spent $3.75 for 3 pounds of granola, the unit rate is $3.75 ÷ 3 = $1.25 per pound.

What is a rate table?

Back

A rate table is a chart that shows the relationship between two quantities, often displaying how one quantity changes in relation to another. It helps in identifying patterns and calculating unit rates.
