Answer: 6.5 quarts
Step-by-step explanation: In this problem, we are asked to convert 13 pints into quarts. We will 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 larger unit "quarts" and when we convert from a larger unit to a smaller unit we divide by the conversion factor.
We will divide 13 by 2 which gives us 6.5 quarts.
Therefore, 13 pints = 6.5 quarts.
