Rates and Unit Rates

The video tutorial explains the concept of rates, focusing on miles per hour (MPH) as a common example. It introduces unit rates, where the denominator is 1, and demonstrates how to convert a rate into a unit rate by simplifying the fraction. The tutorial concludes with a summary of how to compare quantities with different units using rates and unit rates.

What is a rate?

• A unit of distance

• A measure of time

• A comparison of two quantities with the same units

• A type of ratio comparing quantities with different units

Which of the following is an example of a rate?

• 45 apples

• 100 dollars

• 30 minutes

• 60 miles per hour

How do you convert a rate to a unit rate?

• Subtract the denominator from the numerator

• Divide the numerator by the denominator

• Add the numerator and the denominator

• Multiply the numerator by the denominator

What is the unit rate if a car travels 90 miles in 2 hours?

• 90 miles per hour

• 45 miles per hour
