unit rate = total amount ÷ number of units

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.
