Understanding Rates: Part of the Ratio Family

The video tutorial explains how rates are part of the ratio family by reviewing the qualities of a ratio. It distinguishes between ratios and rates, emphasizing that rates compare quantities of different measures, such as miles per hour or price per pound. The tutorial highlights the importance of understanding the constant pattern in rates, which makes them part of the ratio family. It also clarifies the use of the word 'per' in rates, suggesting it can be thought of as 'for every' to better illustrate the concept.

What are the three types of comparisons that ratios can make?

• Part to total, total to part, and rates

• Part to part, whole to whole, and rates

• Part to whole, whole to part, and rates

• Part to part, part to total, and rates

What distinguishes a rate from a standard ratio?

• Rates are always larger than ratios

• Rates compare quantities of different measures

• Rates are only used in speed measurements

• Rates compare quantities of the same measure

Which of the following is an example of a rate?

• Three miles per two hours

• Three cats to two dogs

• Three boys to two girls

• Three apples to two oranges

Why is 'miles per hour' considered a rate?

• Because it compares two quantities of the same measure

• Because it uses the word 'per'

• Because it compares distance and time, which are different measures

• Because it is a common unit of speed

What does the word 'per' signify in a rate?

• A constant pattern or relationship

• A comparison of identical measures

• A comparison of similar quantities

• A temporary relationship

How can the concept of 'per' be rephrased to better understand rates?

• As 'for every'

• As 'for each'

• As 'for all'

• As 'for some'

What is the constant pattern in rates that makes them part of the ratio family?

• They maintain a consistent relationship between different measures

• They always decrease

• They fluctuate randomly

• They always increase
