Diego can fill 1 1/5 bottles with 3 liters of water how many liters of water fill 1 bottle?

Answer 1

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
