Answer :
There are 2 pints in a quart. Convert them both to the same measurement. Let's say you convert them both to pints. Multiply. Do 13 times 2. This equals 26. Now it is even, they are both in pints. 25 pints to 26 pints (or 13 quarts). 25 pints is less than 13 quarts. (25 pints < 13 quarts)
ratio/ proportion
2 pints= 1 quart
2 pints/ 1quart= 25 pints/ x quarts
x= 12.5 quarts
therefore 25 pints is less than 13 quarts
hope this helps
