Answer: 6 quarts
Step-by-step explanation: In this problem, we are asked to convert 12 pints into quarts which means we use the conversion factor for pints and quarts.
Conversion factor ⇒ 2 pints = 1 quart
Next, notice that we are converting from a smaller unit "pints" to a smaller unit "quarts" and when we convert from a smaller unit to a larger unit we divide by the conversion factor.
So, we divide 12 by our conversion factor which is 2.
12 ÷ 2 = 6
Therefore, 12 pints = 6 quarts.
