Answer:
5/2 liters, which is equal to 2 1/2 liters per 1 bottle
Explanation:
I see that this problem works with fractions, so I will assume that the final answer must be as such.
1 1/5 is the same as saying 6/5, so how many bottles would 1 liter fill?
(6/5 bottles)/(3 liters) = 2/5 bottles per liter
So two liters would fill a single bottle only 4/5 of the way. What about the last 1/5?
Keep in mind that 1/5 is half of 2/5, so (1 liter)/2 = 1/2 liter
So therefore, you can either add 1/2 a liter to 2 liters, or subtract a liter from 3 liters to get 2 1/2 liters per bottle.
Another way to do this problem is as follows:
The ratio we’re looking at is 3 liters for every 6/5 of a bottle
(3 liters) / (6/5 bottles)
We can invert 6/5 before multiplying out the fraction making this process easier
3 * 5/6 = (3*5)/6
Remember that 6/3=2
So we get 5/2 liters, which is equal to 2 1/2 liters per 1 bottle
