Unit Rates

A unit rate is a comparison of two different quantities where one of the quantities is expressed as a quantity of one. For example, if you buy 3 pounds of granola for $3.75, the unit rate is the cost per pound.

To calculate a unit rate, divide the total amount by the number of units. For example, if you spend $40 on 5 pounds of concrete, the unit rate is $40 ÷ 5 = $8 per pound.

To find the unit rate, divide the total cost by the number of bottles: $15.99 ÷ 18 = approximately $0.89 per bottle.

The unit rate is $3.75 ÷ 3 = $1.25 per pound.

The price per gallon is $46.80 ÷ 13 = $3.60 per gallon.

Rounding to the nearest hundredth means adjusting the number to two decimal places. For example, 0.923 rounded to the nearest hundredth is 0.92.

0.923 mL rounded to the nearest hundredth is 0.92 mL.

The unit rate is $40 ÷ 5 = $8 per pound.

A unit rate in terms of cost per item is expressed as the total cost divided by the number of items, resulting in a cost per single item.

The unit rate is $15.99 ÷ 18 = approximately $0.89 per bottle.
