7. Simplify Each Ratio 1) 4) 2) 5) 3) 6)

8. Rate
Rate: is a ratio that compares two quantities with different units of measure.
To solve a rate you divide
Example: people read 50 pages
Unit Rate: is a rate that is reduced to 1 unit ?
$12.00 = =
6 oz
1 oz

9. Rate A comparison of a number to one in different units.
Always written as a single number on a per unit basis.
Always write the units.
Divide to simplify.

10. Simplify Each Rate 2) 1) 3) 4)
Notice all of the rates are written as fractions and are in simplest form!

11. Unit Rate
Rates are simplified by writing them as a unit rate.
A unit rate has a second term that
is a single unit.
Example: 500 people go to 10 school dances.

12. Unit Rate Find the Unit Rate. Amount per one
1) 84 students in 4 classrooms

2) $30 for 6 lunches

14. Unit Rate Find the Unit Rate. Amount per one
3) 10,000 cars sold by 2000 dealers

15. Unit price is the same as unit rate, but
you divide the $ by the number of items.
Example: For a dozen roses it costs $ What is the unit price?

A comparison of a number to one in different units.
Always written as a single
number on a per unit basis.
Always written as two numbers.
Never write the units.
Always write the units.
Reduce to simplify.

22. Unit Rate
Unit Rate is a comparison of a number to one in different units.
It is written as a fraction.
You divide to simplify and always include units in your answer.
1) 120 students in 4 classrooms
2) 29 grams per cubic centimeter
Unit Rate is a rate that is reduced to 1 unit

23. Unit Price Unit price is the same as unit rate, but
you divide the $ by the number of items.
Example: For a dozen roses it costs $ What is the unit price?
