Start by listing the information from the problem.

A fudge sundae comes with 4 fluid ounces of hot fudge. You can write this rate as a fraction:

4
fl oz
.
The ice cream parlor staff has 10 gallons of hot fudge.

The problem asks how many fudge sundaes the staff can make, but that depends on how many fluid ounces of hot fudge they have. So, start by converting 10 gallons into fluid ounces.

There are 128 fluid ounces in 1 gallon, so multiply by

128

fl oz

The result will be in fluid ounces since the units of gallons cancel out.

1,280

fl oz

The staff has 1,280 fluid ounces of hot fudge. To find how many fudge sundaes they can make, multiply by

fl oz

The result will be a number of sundaes since the units of fluid ounces cancel out.

The staff has enough hot fudge to make 320 sundaes before running out.
