Unit Rate Check-in

How are rates and unit rates different?

• A rate has a denominator of 1.  A unit rate does not.
• A rate is just like a fraction.  A unit rate is a ratio.
• Rates involve a measurement of time, but unit rates do not.
• A rate compares two different quantities.  A unit rate has a denominator of 1.

Which of these is a unit rate? Choose all that apply.

• 11 miles per 3 minutes

• 55 liters per gallon

• 2 feet per 2 hours

• $4.50 per hour

• 2 teachers for 10 students
