Unit Rate Examples
Price per pound
$12 for 3 pounds gives $12 ÷ 3 = $4 per pound.
Miles per hour
150 miles in 3 hours gives 150 ÷ 3 = 50 miles per hour.
Items per bag
24 apples in 6 bags gives 24 ÷ 6 = 4 apples per bag.
Unit Price vs Unit Rate
Unit price is a common kind of unit rate. It compares money to one item, pound, ounce, liter, or other buying unit. Use unit price to compare packages that have different sizes.
Common Unit Rate Mistakes
Dividing in the wrong direction
To find amount per unit, divide the total amount by the number of units.
Using zero units
You cannot divide by zero. The unit count must be nonzero.
Forgetting the labels
The labels make the result meaningful, such as dollars per pound or miles per hour.
