Nine Bottles Hold 4.5 litres of water altogether? how many will 5 bottles hold?

5(4.5 / 9) = ______ liters

To determine how many bottles 5 bottles will hold, we need to find the ratio between the number of bottles and the amount of water they hold.

We know that 9 bottles hold a total of 4.5 liters of water altogether. To find the ratio, we divide the total amount of water by the total number of bottles:

Ratio = Total amount of water / Total number of bottles

Ratio = 4.5 liters / 9 bottles

Ratio = 0.5 liters per bottle

Now, to find how many bottles 5 bottles will hold, we multiply the ratio by the number of bottles:

Number of bottles = Ratio * Number of bottles

Number of bottles = 0.5 liters per bottle * 5 bottles

Number of bottles = 2.5 bottles

However, we can't have a fraction of a bottle, so the answer would be that 5 bottles will hold approximately 2 full bottles of water.
