Learning goal: Define, solve and create rates and unit rates.

*6-2 Rates and Unit Rate.

*Rate

*A ratio that compares TWO quantities with different units

*Ex: 160 beats every 2 minutes

*Unit Rate

*When a rate has a denominator of 1

*Ex: miles per hour

Page 3: Learning goal: Define, solve and create rates and unit rates

*When writing rates…

*Always remember to keep the denominator of 1.

*Time on bottom

*Money ($) on top

*Think about what makes sense

Page 4: Learning goal: Define, solve and create rates and unit rates

*Write each unit rate*Ex: 360 miles in 6 hours

*Ex: 160 people for 5 classes

Always write the units!!!

Examples: miles, hours, classes.

Page 5: Learning goal: Define, solve and create rates and unit rates

*Example

*If it costs $2 for 8 juice boxes, what is the unit rate?

Page 6: Learning goal: Define, solve and create rates and unit rates

*What’s the better buy?

*8 pound bag of dog food for $9.88

*20 pound bag of dog food for $23.44

Page 7: Learning goal: Define, solve and create rates and unit rates

* Your Example!! =

*Ben can type 153 words in 3 minutes. At this rate, how many words can he type in 10 minutes?
