Frequently Asked Questions
What is a unit rate?
A unit rate is a ratio that compares a quantity to one unit of another quantity. For example, if 12 items cost $36, the unit rate is $3 per item. The denominator of a unit rate is always 1.
How do you find a unit rate?
Divide the total by the number of units. For example, 150 miles in 3 hours: 150 ÷ 3 = 50 miles per hour.
What is the difference between a rate and a unit rate?
A rate compares two different quantities (like 150 miles per 3 hours), while a unit rate expresses that comparison per one unit (50 miles per 1 hour, or simply 50 mph).
How can unit rates help with shopping?
Unit rates let you compare prices fairly. If a 12-pack costs $6.00 ($0.50 each) and a 20-pack costs $9.00 ($0.45 each), the unit rate shows the 20-pack is a better deal per item.
