To calculate the number of gallons in 10 quarts use the following steps:

1) Find the number of quarts in 1 gallon (4).

2) Divide the number of quarts (10) by the number of quarts in 1 gallon (4)

10/4 = 2 2/4 or 2 1/2

3) Label the answe with "gallons"

10 quarts = 2 1/2 gallons

There are 2.5 gallons in 10 quarts.

Use the unit conversion factor:

1 US quart = 0.25 US gallons

Then multiply out to cancel quart units and end up with gallons:

10 quarts * (0.25 gallons / 1 quart) = 2.5 gallons.

There are 4 quarts in 1 gallon. So there are 8 quarts in 2 gallons. The 2 extra quarts here would fill a half a gallon.

So there are 2 and a half gallons in 10 quarts.

Note that we are talking about US liquid quarts and gallons.

There are four quarts in a gallon. Divide 4 into 10, and you have 2 gallons, with 2 quarts left over, which is a half gallon left over. The answer is 2 1/2 gallons.

...A quart is a quarter of a gallon, or, 2 pints, so, there are 8 pints in a gallon.

10 quarts = 20 pints so....

.... 20 / 8 = 2.5 gallons!
