Fill up the the 4 container and twice and pur both into th 7. You get 1 in the 4 and the 7 is filled. DUmp out the 7. Put the 1 in the empty 7. Fill up the 4 and pur it into the seven to get 1+4=5.

Fill the  7

 

Pour  into  4

 

We  have

 

3 in 7      and   4  is full

 

Pour out 4.....fill wth  the  3  in the  7

 

So we have

 

3 in 4  and  0  in 7

 

Fill up 7, pour  1  into 4

 

We  have

 

4 in 4  and  6  in 7

 

Pour  out  4.....fill  4  from 7

 

We  have 

 

4 in 4  and  2 in 7

 

Pour  out  4, fill with 2 in 7

 

We  have  2 in 4    and 0 in 7

 

Fill  7    and pour 2 into 4

 

7 now contains  5

 

 

cool cool cool
