Pour from the 7 liter container into the 5 liter container until their levels are equal. Both containers will then have 6 liters in them.
You got to put 4 liters in the 5 liters jar. fill up the 7 LJ (liters jar), pass the liquid to the 5 LJ, and discard it. Now you have 2 liters in the 7LJ pass to and keep it in the 5 LJ. Do it again, now you have 4 liters in the 5LJ. Fill up the 7 LJ, and use it to fill the 5 LJ ( it will pour just one liter) And you will have 6 liters inside de 7 LJ. =D
# Fill the 5 liter bucket # Pour it into the 7 liter bucket # Fill the 5 liter bucket # Fill the 7 liter bucket from the 5 (2 liters go in leaving 3 liters in the 5 liter bucket) # Empty the 7 liter bucket # Pour the 3 liters from the 5 liter bucket into the 7 liter bucket # Fill the 5 liter bucket # Fill the 7 liter bucket from the 5 liter bucket (4 liters go in leaving 1 liter in the 5 liter bucket) # Empty the 7 liter bucket # Pour the 1 liter form the 5 liter bucket into the 7 liter bucket # fill the 5 liter bucket. You now have 5 liters in the 5 liter bucket and 1 liter in the 7 liter bucket; 6 liters in all. Pour the 5 liters into the 7 liter bucket if you want all 6 liters in one container.
7, 5 Liter jars 7, 0 = fill 7 liters jar 2, 5 = transfer to the 5 liters jar 2, 0 = emtry the 5 liters jar 0, 2 = transfter to 5 liters jar 7, 2 = fill in the 7 liter jar 4, 5 = transfer 7 liter to 5 liter jar 4, 0 = emtry to 5 liters jar 0, 4 = transfer to 5 liters jar 7, 4 = fill in 7 liter jar 6, 5 = transfer 7 liter to 5 liter jar Fill the 7 liter jar and tip into the 5liter jar. you now have 2 litres in the 7 liter jar, empty the 7 liter and tip the 2 liters into the 5liter jar. Fill the 7liter and tip into 5 liter, you now have 4 liters in the 7 liter jar, empty the 5 liter jar and put 4liters from 7 liter jar into it. Again fill the 7 liter jar, 1 more liter will fill the 5 liter jar so empty the 7 liter into the 5 liter, 6liters left in the 7 liter jar;-)
6.5 - 7 bottles
5 + 6 + 7 = 18
1)Transfer 7 liters from the 12-liter jar into the 7-liter jar.We now have 5 liters in the 12-liter jar and 7 liters in the 7-liter jar. The 5-liter jar is empty, as of now.2)Transfer 5 liters from the 7-liter jar into the 5-liter jar.The 12-liter, 7-liter, 5-liter jars now contain 5, 2 and 5 liters respectively.3)Empty the contents of the 5-liter jar into the 12-liter jar.The 12, 7, 5- liter jars now contain 10, 2 and 0 liters respectively.4)From the 7-liter jar, take out 5 liters and pour 7 liters from the 12-liter jar into the 7-liter jar.We now have 3 liters in the 12-liter jar and 7 in the 7-liter one, while the 5-liter jar has only two liters in it.5)Fill up the remainder of the 5-liter jar using the 7-liter jar.That leaves us with 3 liters on the 12-liter jar and 4 liters in the 7-liter jar. The 5-liter jar is full.6)Pour the contents of the 5-liter jar into the 12-liter jar.There are 8 liters in the 12-liter jar and 4 liters in the 7-liter jar, while the 5-liter jar is empty.7)Pour the 4 liters that are in the 7-liter jar into the 5-liter jar.We now have 8 liters in the 12-liter jar and 4 liters in the 5-liter jar. The 7-liter jar is empty.8)Fill the 7-liter jar using the 12-liter jar.There is now only 1 liter in the 12-liter jar and 7 liters in the 7-liter jar and 4 liters in the 5-liter jar.9)Fill up the 5-liter jar using the 7-liter jar.There is now 1 liter in the 12-liter jar and 6 liters in the 7-liter jar and 5 in the 5-liter jar.NOTE: This might not be the only way, or the shortest way to do it.
5*6 -7 +1 +0
(5+7)*(8-6)=24
5 and 9/7 = 6 and 2/7
8 plus 7 divided by 5 then add 6.
(8 + 5)*(7 - 6) = 13*1 = 13
4 x 6(7+5)*(6-4) = 24
