Chapter 1.1 - Unit Rates

Learning Target: I can define and calculate unit rates.

Remember ratios???...

A ratio compares two quantities.

 

For example, 160 heartbeats per 2 minutes or 4 inches by 3 inches.

 

Ratios can be written in three forms: 2/3, 2:3 or 2 to 3.

A unit rate is a ratio that compares two measurements where the quantity in the denominator is 1.

 

For example, 55 miles per hour or 60 words per minute.
