Understanding Rates and Unit Rates

The video tutorial introduces the concept of rates and unit rates, explaining that a rate is a comparison of two quantities with different units, such as dollars per cheeseburger. A unit rate is a rate with a denominator of one, like miles per hour. The tutorial provides examples, including calculating average speed and cost per item, to demonstrate how to find unit rates by dividing the given quantities.

What is a rate?

• A comparison of two quantities with no units

• A comparison of three quantities with different units

• A comparison of two quantities with different units

• A comparison of two quantities with the same units

What is a unit rate?

• A rate with a denominator of one

• A rate with a denominator of two

• A rate with a numerator of one

• A rate with a denominator of zero

If Jennifer travels 348 miles in 6 hours, what is her average speed?

• 68 miles per hour

• 48 miles per hour

• 58 miles per hour

• 78 miles per hour

How do you calculate the unit rate for distance and time?

• Subtract the time from the distance

• Add the distance and time

• Divide the distance by the time

• Multiply the distance by the time

What is the cost per granola bar if a pack of 24 costs $5.04?

• 23 cents per bar

• 21 cents per bar

• 19 cents per bar

• 25 cents per bar

How do you find the cost per item in a package?

• Multiply the total cost by the number of items

• Divide the total cost by the number of items

• Add the total cost and the number of items

• Subtract the number of items from the total cost

What is the first step in calculating a unit rate?

• Multiply the quantities

• Ignore the units

• Add the quantities together

• Identify the units involved

Why is it important to understand unit rates?

• To simplify complex calculations

• To compare quantities with the same units

• To avoid using any units

• To make informed decisions based on comparisons

What is the final step in calculating a unit rate?

• Add the result to the original rate

• Ensure the denominator is one

• Divide the result by the original rate

• Multiply the result by two
