Richard and sales are making cranes. they use 1 piece of blue paper and one piece of orange paper to make it. the blue paper comes in packs of 3 and the orange paper comes in packs of 6 . what is the least number of cranes can they make without any supplies left over. u

Because the orange paper comes in packs of 6, we know that they have to make at least 6. Fortunately, the blue paper comes in packs of 3, so they can buy 2 packs of blue paper and 1 pack of orange paper to make that minimum amount of cranes. Therefore, the solution is 6. 

6. 
Note: That's kinda a strange way of making cranes, using 2 pieces of paper.
