If Each bottle uses 1/4 Gallon (0.25 Gallon) then in order to find how many bottles of lotion Jill will be able to make with 3 Gallons, you would need to divide the 3 Gallons by the amount each bottle needs, like so...
3 gallons / 0.25 = # of Bottles
3 gallons / 0.25 = 12 Bottles
After doing this small calculation we can see that from the 3 Gallons Jill will be able to make a total of 12 Bottles of Lotion
