Contest 7-Lets go to the river!
We have two clay pitchers as the ones in the image below, they have the particularity that both of them do not have marks, this mean, we can not measure theirs contents. We do know that one pitcher has eleven (11) liters total capacity and the other has seven (7) liters total capacity. Using only these clay pitchers and a wealthy river, maybe the river near where Mr. Pippin lives! How we can get exactly six (6) liters of water?
Tenemos dos cántaros de barro como los mostrados en la figura, con la particularidad de que ambos carecen de marca alguna; esto es, su contenido no se puede medir. Sólo sabemos que uno tiene once (11) litros de capacidad y el otro siete (7). Usando únicamente los dos cántaros y un río caudaloso, quizás el rió cercano a donde vive Mr. Pippin! ¿Cómo podemos conseguir exactamente seis (6) litros de agua?

How fun!! My children and I worked on it and think we came up with an answer!
Fill the 7 liter jar with water; pour water into the 11 liter jar. This makes 7 liters in the 11 liter jar.
Again, fill the 7 liter jar with water and pour as much from it as will fill the 11 liter jar (4 liters fit). This makes 11 liters of water in the 11 liter jar and 3 liters of water will remain in the 7 liter jar.
Empty the 11 liter jar.
Pour the 3 liters from the 7 liter jar into the 11 liter jar.
Fill the 7 liter jar with water.
Pour the 7 liters of water from the 7 liter jar into the 11 liter jar, which already has 3 liters of water in it, thus resulting in 10 liters of water total in the 11 liter jar.
Fill the 7 liter jar with water. Pour as much of this water into the 11 liter jar. Only 1 liter of water will fit in the 11 liter jar, leaving 6 liters of water in the 7 liter jar. (Empty the 11 liter jar so that you will only have 6 liters of water in both jars).
Added to clarify:
In the last paragraph the 2nd sentence should read: “Pour as much of this water into the 11 liter jar as will fit.”
yeeeees, You are correct, It is fun to do math this way! Congratulations!
