Divide 560,444 by 350

560,444

________

350

Now, the answer won't give an even number; it'll be a number plus a fraction. Since you can buy half a 0.35 of a gallon of paint, and since the questions asks for the result in gallons, logically you probably have to round the number of to the next highest round number.

For instance, if the calculation says you need 1000.156 gallons of paint, that means you need 1001 gallons of paint, because you can't buy 0.156 gallons of paint, as a practical matter.
