The Giant One is used to reduce rates. A rate is in simplest form, or is reduced if the numerator and denominator have no common factors other than one.

To find the simplest form divide the numerator and denominator by the greatest common factor.

Rate: is a ratio that compares two quantities with different units of measure. To solve a rate you divide Example: 10 people read 50 pages Unit Rate: is a rate that is reduced to 1 unit ? $12. 00 = 6 oz 1 oz =

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.

1) 3) 2) 4) Notice all of the rates are written as fractions and are in simplest form!

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.

Unit price is the same as unit rate, but you divide the $ by the number of items. For a dozen roses it costs $36. 00. What is the unit price? Example:

Jenna buys 8 oranges for $2. What is her unit price? Unit Price: Divide the $ by the amount

Michael buys 7 movie tickets for $42. 00 What is his unit price? Unit Price: Divide the $ by the amount

Which is the better deal? 20 oz. of orange juice for $1. 35 1 quart (32 oz. ) of orange juice for $2. 40

Which is the better deal? A 16 oz box of cereal costs $2. 89 and a 20 oz box costs $3. 49. Which is the better buy? 16 oz. of cereal for $2. 89 20 oz. of cereal for $3. 49

Ratio vs. A comparison of two whole numbers in the same units. Always written as two numbers. Never write the units. Reduce to simplify. 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.

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

Unit Price Unit price is the same as unit rate, but you divide the $ by the number of items. For a dozen roses it costs $36. 00. What is the unit price? Example:
