Lily buys 3 gallons of milk. How many quarts of milk did she buy?
12
To find out how many quarts of milk Lily bought, we first need to know the conversion rate between gallons and quarts. Since there are 4 quarts in a gallon, we can calculate the number of quarts by multiplying the number of gallons by 4.
In this case, Lily bought 3 gallons of milk. To find out how many quarts that is, we multiply 3 by 4.
3 gallons * 4 quarts/gallon = 12 quarts
So, Lily bought 12 quarts of milk.
