Electronic circuit ratio problem for purple potion about kirkmcdonald.github.io

[DRY411S]

The calculator is correct.

For the 8 + 1/3 electronic circuit machines you need 3/2*(8 + 1/3) = 12 + 1/2 copper cable assembling machines (not 25 as you suggest)

For the 40 advanced circuit machines, you need ANOTHER 6 + 2/3 copper cable assembling machines

12 + 1/2 + 6 + 2/3 = 19 + 1/6 (as calculated)
