First, pour the 8l of water into the 7l container. so thr will be 7l in 7l container. then pour it into the 5l container.

7l container: 2l
5l container:5l
8l container: 1l
3l: 0l

Now, pour 5l of the water into the 8l container.

8l container: 6l
5l container: 0l
3l: 0l

then u continue yrself, i g2g, the rest is obvious.

The trick here is to understand that you can measure the difference between any two containers, as well as the contents of a single container.

For example, to measure out one liter, you fill up the 8 liter container and then from that fill up the 7 liter container. The remainder in the 8 liter container gives you 1 liter.

So...
8 - 7 = 1
5 - 3 = 2
3 you have directly
2 + 2 = 4
5 you have directly
5 + 1 = 6
7 you have directly

So you can divide the water into any one liter increment.

To divide the 8 liters equally, fill the 7 liter container from the contents of the 8 liter container, leaving 1 liter in the 8 liter container. Then, from the 7 liter container, fill the 3 liter container, leaving 4 liters in the first. Finally, pour the contents of the 3 liter container into the 8 liter container, which until now contained only 1 liter of liquid. The 3 plus 1 liter then make 4 liters contained in the 8 liter container. The other 4 liters remain in the 7 liter container, and the 8 liters of liquid are now divided evenly.

Hi Amon, I only thing i came up with,is put 7,5,3 litres containers in a roll by each other,and pour each container at a slow pace,until they all have equal amounts of water. That counting 8 litre container too.

Place the containers side by side and pour a little at a time until it is even.

Divide the 8 liters into what?

2007-01-22 19:13:09 · answer #6 · answered by Northstar 7 · 0 1

pour the water from the 8L bottle and fill the 7L bottle

pour the 7L bottle and fill the 5L bottle

Pour the 5L bottle and fill the 3L bottle

pour the 3L bottle back into the 8L bottle and then pour about half back to the 3L bottle till they are approximately level with each other. all 4 bottles now have 2L
