Hey,

I can't do this exercise for some reason - am I missing something? I find it a bit confusing and there are no hints provided. The question is:

The starting block is 13/12 units long. Use the tools to the right to convert the starting block into the goal block that is 3/12 units long. You can see your progress as the current block.

You would think that dividing the 13/12 block into 13 pieces and then copying it 3 times would work, but it doesn't. If I try to divide by 13 it says it's wrong.

Best wishes,

Hauke
