To convert quarts to gallons, you can use the conversion factor that 4 quarts equals 1 gallon.
To find out how many gallons are in 12 quarts, you can divide the number of quarts by the number of quarts per gallon:
\[ \text{Gallons} = \frac{\text{Quarts}}{4} \]
Using 12 quarts:
\[ \text{Gallons} = \frac{12}{4} = 3 \]
So, there are 3 gallons in 12 quarts.
