Asked by CeCe 4gr

There are 7 marbles in a circle. How could you get all 7 marbles ito a box by moving them in groups of only 2 or 3 at a time? You must follow this rule: Groups of 2 may ONLY move right,and groups of three may ONLY move left. How could you move all 7 marbles from a circle to a box?

Answer can not be too complicated!

Is the box to the right or left of the circle?

Answered by CeCe 4gr
The right.
Answered by Ms. Sue
Move the first six in three moves (2 each time). That leaves 6 in the box and 1 in the circle.

Now move 3 from the box to the circle. Can you see what you'll do from there?
