G6 Rate and Unit Rate Practice for the Assessment

Front

What is a rate?

Back

A rate is a ratio that compares two different quantities, often expressed as a quantity per unit of time, such as miles per hour.

Front

What is a unit rate?

Back

A unit rate is a rate in which the second quantity is one unit. For example, if a car travels 300 miles in 5 hours, the unit rate is 60 miles per hour.

Front

How do you calculate the unit rate?

Back

To calculate the unit rate, divide the first quantity by the second quantity. For example, if you have 150 miles in 3 hours, the unit rate is 150 ÷ 3 = 50 miles per hour.

Back

The best value is the option that gives the lowest cost per item or the highest quantity for a given price.
