How do I expres a rate as a unit rate

Usually it is rate/unit said as "rate per unit."
Examples are "miles per gallon" and "price per pound."

I hope this helps. Thanks for asking.

four gallons of gasoline weigh 25 pounds. find the unit rate in dollars per ounce

To express a rate as a unit rate, you need to divide the quantity by the unit of measure. Here's an example to help explain:

Let's say you traveled 250 miles and used 10 gallons of fuel. To find the unit rate, divide the miles by the gallons:

250 miles ÷ 10 gallons = 25 miles per gallon

So the unit rate for this example is 25 miles per gallon.

To express a rate as a unit rate, simply divide the quantity by the unit of measure, and ensure that the unit of measure is included in the result.
